Well, hello and welcome back to Impact Quantum, the podcast for the quantum
Speaker:curious. We. We firmly
Speaker:believe you don't need to be a PhD, although it certainly helps
Speaker:to participate in this emerging field. And with me is the most quantum
Speaker:curious person I know, Candice Gahooley. How's it going, Candice?
Speaker:It's great. Thank you so much, Frank. You know, today
Speaker:it's crazy. This week actually we got a massive, massive snowstorm.
Speaker:And although where I am in Montreal, Quebec, we always see the
Speaker:first flakes for Halloween, we normally don't have such
Speaker:a deluge. I probably have nine inches outside.
Speaker:It's, it's just crazy. So I'm all looking at the beautiful
Speaker:snow, but I'm getting my, my head all in gear to have a great conversation
Speaker:today. I'm really excited about our guest. Yeah, awesome.
Speaker:It is chilly down here. We didn't get any snow, although I think in Western
Speaker:Maryland they did get some snow, but it is chilly here
Speaker:and I may have to fire up the GGX to do some fine tuning
Speaker:to heat up my office as well as turn on some of these monitors.
Speaker:So who do we have talking to us today? Candace. Right, so today we're talking
Speaker:to Mahmoud Sabuni. He is the lead
Speaker:quantum processor engineer at
Speaker:oqd. Very cool. Hi, how are you today?
Speaker:Okay. Yeah, thanks for having me here.
Speaker:Yeah. Here also we have a little bit of snow, like last couple
Speaker:of days still like leaves on the trees, but you could
Speaker:see the snow and then snow and then after that you see the
Speaker:leaves on top of the snow. That's kind of interesting feature that
Speaker:you could see. So you're also in Canada, right? Yeah, yeah, in
Speaker:Waterloo, Canada. Okay, very cool. For the people who know, don't know,
Speaker:like Waterloo, where is it? Like close to the Toronto, like 70 or 80
Speaker:kilometers south. Yes, that's.
Speaker:I'm here from probably almost like 10 years.
Speaker:Start by like some postdoc and some other activity at
Speaker:Google as the optical engineer and then back
Speaker:to this open quantum design startup
Speaker:in Waterloo. Oh, very cool, very cool. Your
Speaker:LinkedIn is very impressive. So I have plenty of questions around
Speaker:that. Open quantum design.
Speaker:Tell me about that. That's an interesting.
Speaker:What does open quantum design do? Or. Yes, that's.
Speaker:Yeah, that's probably the core of the Discussion that we can go through.
Speaker:First of all I'm more like a hardware person. Like I worked more on the
Speaker:hardware side on like quantum information since my
Speaker:PhD which was in in Sweden in Europe
Speaker:and also my master there around the quantum
Speaker:information technology and like storage
Speaker:basically quantum memory during my PhD and after after
Speaker:that I came to the like quantum computing parts
Speaker:and as a postdoc here at iqc.
Speaker:And yeah I just put some gap for the
Speaker:Google time which was more classical optics and hardware. But later
Speaker:like there is some three PI here in Waterloo.
Speaker:Two of them Crystal Senko and Raj Wolselm working on the
Speaker:Ion Trap machine and one Roger Molko
Speaker:working more on on more AI and software side.
Speaker:They decided to start making like an
Speaker:iron trap based full stack quantum computer.
Speaker:This company start from like a February 24th and
Speaker:I joined them at the at the same time then we
Speaker:the idea is to have a full stack quantum
Speaker:computer based on iron trap available for anyone who
Speaker:wants to rebuild it. Like the
Speaker:way that we do is that we have like some software team
Speaker:and some hardware team. I'm more on the hardware side and we are
Speaker:developing like some prototype and at the same time we
Speaker:put all our designs on GitHub available
Speaker:for like anyone who wants to rebuild or use
Speaker:that kind of module for for his setup in future.
Speaker:And the the big picture is to like do the same thing
Speaker:that happens for either software or some even hardware
Speaker:in the classical computers in the quantum
Speaker:computers. Like there are some like you can explain more details like
Speaker:what kind of reasonings is behind this will be successful or not
Speaker:that. Yeah we don't know but we're pushing that. And during
Speaker:last year we could reach to some good milestones.
Speaker:We could get some collaborators like
Speaker:partners. We have like five different companies already
Speaker:putting money or full time employee on this open source
Speaker:activity and we are pushing towards
Speaker:getting our first aspect of the machine out soon.
Speaker:Hope like January 26th that shows okay this machine
Speaker:is already live and available and yeah
Speaker:looking for more people to come and contribute to see
Speaker:how we can push it forward. That's the more like
Speaker:a central activity of the open quantum design.
Speaker:So in practice
Speaker:what does open quantum hardware design mean
Speaker:in practice and how is it different from traditional
Speaker:closed or proprietary approaches in physics
Speaker:research? Yes like
Speaker:if we want to make very similar example in the
Speaker:classical world I could bring example of the
Speaker:RISC V company that's a company
Speaker:that actually we have some people from there also like
Speaker:with the same idea came to the one quantum design as a board member
Speaker:to Push the idea here also in 80s and
Speaker:90s there was like discussion about the
Speaker:designing of the CPUs. Like different
Speaker:companies like closed or open just start
Speaker:to work on that kind of architectures. And then
Speaker:at some point RISC V as an open source company
Speaker:start building the standards or
Speaker:designing chips. And these days like that
Speaker:the RISC V it has already
Speaker:70 plus members. And then most
Speaker:of the CPU design in Intel AMD anywhere else
Speaker:it's using those standards that's built on the open
Speaker:source activities. The same idea
Speaker:here also could be in principle
Speaker:implemented. Like for example
Speaker:benchmarking of the quantum computer is something
Speaker:which is very tricky. Like different company. Like
Speaker:+10 different companies already announcing different
Speaker:like machine. And then we don't have still
Speaker:fully standard benchmark system to do
Speaker:the benchmarking on different machine. And
Speaker:one of the reason is that those machines are closed and that
Speaker:no one have access to those machines to test and
Speaker:benchmark them. Then if they have some machine at
Speaker:least in some of the architectures like Ion Trap
Speaker:or in future could be other others also you
Speaker:can run your algorithm on that machine and
Speaker:tested machine and then test your standards and then write the standards
Speaker:based on those open access machine for anyone around the world.
Speaker:And then the rest of the people can also use that. This
Speaker:is not against any like a
Speaker:IP based company also like they could also get benefit of this
Speaker:open source and build the standard around that.
Speaker:Because around this like a point people can come
Speaker:and exchange idea and also develop
Speaker:whatever that they have done so far. And then
Speaker:integration of those like multi
Speaker:idea people can
Speaker:in principle maybe outperform
Speaker:the flow system.
Speaker:That's the idea behind this. But there is some other
Speaker:feature also would be interesting from hardware point of view. Because from
Speaker:software point of view you can see a lot of comparison
Speaker:around the board. For example Linux versus Windows
Speaker:like maybe the top
Speaker:like the most important project around the world
Speaker:running Linux, not Windows like Linux is the open source
Speaker:that's in the software. It's very clear that
Speaker:that's a path that can be very successful
Speaker:in the hardware regime. Especially in
Speaker:quantum computation.
Speaker:Very expensive hardware you need to develop. And then the open
Speaker:source community will have difficulty to
Speaker:gather those together and then test whatever they
Speaker:want to do on that hardware. The idea on OQD
Speaker:is to make that kind of test beds for
Speaker:anyone who want to work to single
Speaker:details of the machine. Like
Speaker:other machine that is available already mainly is cloud based.
Speaker:You can run some algorithm on those but
Speaker:you don't have access to full ingredient of that
Speaker:machine. Yeah, that's simply because of the IP reason.
Speaker:But here everything is transparent. You can see
Speaker:each single module.
Speaker:For that reason it will be easier to
Speaker:first benchmark it second also learn it
Speaker:from this hardware available. A lot of
Speaker:people like a software oriented that they are interested
Speaker:to run some calibration on some real quantum machine.
Speaker:They can do that and
Speaker:that's a big benefit on the learning curve.
Speaker:Like build some better workforce development.
Speaker:Or even for closed system they can use this kind of people
Speaker:who know it's capable of doing
Speaker:something which was not possible without access to the hardware.
Speaker:That's one big plus. And also
Speaker:like for example colleges that they
Speaker:want to train some quantum engineer at the bachelor level that
Speaker:they want to handle quantum machine.
Speaker:They can use this kind of system. Like they cannot
Speaker:go and buy some quantum computer from like big IP based
Speaker:company and then have access to all full details because
Speaker:it's IP based. But here they can have
Speaker:machine and then run it and learn it
Speaker:and improve it for whatever
Speaker:purpose that they have. This machine is not necessary to be the top best
Speaker:machine in the world. It's just need to run some simple
Speaker:functionality. And
Speaker:because of the reason that I mentioned like benchmarking, you can do it on a
Speaker:simple machine learning, you can do it on the simple machine. And
Speaker:also workforce development also you can. Do
Speaker:on this machine with the open design
Speaker:transparency, open source. Do you find that this
Speaker:accelerates innovation? That sharing
Speaker:these designs actually helps solve complex engineering
Speaker:problems, perhaps faster? Yeah, that's the idea.
Speaker:If you want to compare it in physics person. And then I
Speaker:was comparing to some phenomena in. In nature, like
Speaker:comparing the light bulb to the laser. Like the laser
Speaker:happened whenever that you have phase coherences of the
Speaker:photons on top of each other and they will
Speaker:amplify the the final result here also
Speaker:that could be a. Yeah, it's. It's difficult to prove
Speaker:it, but there are some example as I mentioned, like
Speaker:software developmentally and also hardware like this
Speaker:RISC V versus ARM or Intel
Speaker:that shows that was successful here also there's a good
Speaker:chance that can be successful and this comes
Speaker:from like University of
Speaker:Waterloo. Anyway they spend time on
Speaker:development different sections and different modules.
Speaker:And that would be good to share it with the academia first for
Speaker:sure. And then why not share it with everyone
Speaker:and then try to. Also we
Speaker:also could benefit a lot. Like for example we have
Speaker:some locking mechanism under our laser
Speaker:that we don't have much and bandwidth of the people
Speaker:to develop that. But someone else could come and say
Speaker:oh, I did this with all single details. Not
Speaker:just a paper, not the published paper or archive version, just with the
Speaker:details of the electronics, mechanics, optics,
Speaker:diagrams and share those information and then
Speaker:we can build that system in here. On the other hand,
Speaker:the other partner also can benefit from our whatever
Speaker:for example our optical circuit board design which is
Speaker:transparent, everything available and use that as
Speaker:like resources to build its own system
Speaker:in different country completely.
Speaker:Yeah, we have some collaborators like from India,
Speaker:from like Brazil, from a lot of countries
Speaker:in the south hemisphere like coming
Speaker:for this kind of options.
Speaker:And of course there will be also some difficulty in terms
Speaker:of politics that will be challenging to
Speaker:how, when and where you want to distinguish between
Speaker:these open and close and IP base. That's. That's the
Speaker:still open question that yeah, there is some resistance
Speaker:sometimes. So there's a lot to unpack
Speaker:there. But one of the things I saw on
Speaker:your website for OQD was
Speaker:you referenced the term full stack quantum computer. Yes.
Speaker:What is a full stack quantum computer?
Speaker:Full stack means like you can.
Speaker:The whole quantum computer is several
Speaker:layer of different information
Speaker:from your classical computer code
Speaker:and then that will convert to some mid layer and
Speaker:then the mid layer to very low level in the. We call it like a
Speaker:meta layer that you want to talk to the. In our case to
Speaker:atoms and there will be a lot of like exchange
Speaker:in between. In at open quantum
Speaker:design we have some partner that works on the
Speaker:software like for example Xanadu as a IP
Speaker:based company they provide some agreement to
Speaker:OQD and provide some full time employee they can
Speaker:adopt their like a software which is open source
Speaker:to our hardware which also is open source.
Speaker:Like we are working on OQD Aintrap using
Speaker:the Arctic software which is the open source hardware
Speaker:developed by. I think
Speaker:it's from Maryland actually. And
Speaker:these two combination could be as a full stack.
Speaker:Like you can run your code high level and then it will convert everything
Speaker:down to the. To the pulse level. Talking to atoms. Take the
Speaker:data and then plot the data, extract the information
Speaker:and use it. That's the meaning of the full stack. Like
Speaker:from high level to bare metal layer
Speaker:and vice versa,
Speaker:open to everyone. The software
Speaker:in most cases are available
Speaker:like in superconducting qubit in
Speaker:photonics and ion trap. It's a
Speaker:little bit lagging. Like we need some software at the high
Speaker:level. That's this kind of project trying to fill out that
Speaker:gap. And
Speaker:yeah, that's the meaning of the full stack.
Speaker:Interesting. Full stack is one of those terms you hear a lot in technology
Speaker:and it means different things to different people and
Speaker:it Means different things in different contexts too. So that's why when I saw that
Speaker:usually my reaction to the the term full stack it triggers me to
Speaker:flashbacks of conversations I had with recruiters throughout the years.
Speaker:So I'm like no, so
Speaker:so. So I like your definition better. So okay. Yeah, it is here is
Speaker:like a. Like a simpler version that.
Speaker:Yes, that's more reasonable. Version two.
Speaker:Yeah, yeah. Of course for like using the
Speaker:quantum computer you cannot directly go to the
Speaker:bare metal. You need some middle layer which is very
Speaker:crucial and still needs a lot of development
Speaker:connecting those hardware in terms of. Because one of
Speaker:the enemies here that we have in like. Okay. Whatever
Speaker:properties that it will make a lot of difficulty for
Speaker:us is the phase. Phase means
Speaker:like whenever that you have a wave you need to
Speaker:predict exactly at. In future time what is
Speaker:your amplitude. And this could jitter a little bit.
Speaker:And in our hardware side
Speaker:this will be crucial to control this phase.
Speaker:And in the radio frequency
Speaker:hardware that's It's a challenging.
Speaker:That's not in our expertise like
Speaker:a bandwidth in open quantum design. And we are trying to
Speaker:get help from like some expert in the rf.
Speaker:There is nothing available I could say
Speaker:reliable for special
Speaker:for ion trap that you can use it
Speaker:easily and control your. Your ions or your atoms.
Speaker:And even the. In
Speaker:the. In the closed system also which is very expensive.
Speaker:It's not fully functional to control the ions yet.
Speaker:And yeah we have some gap there that we need to
Speaker:fill out. Controlling the phase reliably
Speaker:and in. In an open source community which is as I said is
Speaker:based on the Arctic and Cyanura
Speaker:blocks. It's a company for ion trap. The same like a
Speaker:company like other names coming to the superconducting
Speaker:qubits. Also they're a little bit ahead than
Speaker:ion traps if you want to compare it in that area.
Speaker:Okay. Ion traps you don't really hear.
Speaker:I haven't heard a lot about that lately. What exactly is is an
Speaker:ion trap versus.
Speaker:Superconducting for superconducting? Like what. How does that relate. I
Speaker:know it's one of the hardware kind of families. Yes. Like
Speaker:for any quantum computation you need some
Speaker:species. Some people using photon
Speaker:which is like a photonic based quantum computing like a
Speaker:Xanadu or Psi quantum. They are using photons.
Speaker:Some people using a atom
Speaker:directly single atoms. That's like a neutral atoms
Speaker:like a Q era for example. Using this kind of
Speaker:species to encode the information.
Speaker:And another type of
Speaker:quantum computer that using species of ion
Speaker:means like you have atoms and then you
Speaker:shoot out one of the electrons ionized.
Speaker:Why you make it ionized? Because it will
Speaker:be easier and deeper to trap it.
Speaker:What the trap means like you need to have like
Speaker:atoms and these atoms, single
Speaker:atoms, no interaction with the environment and then
Speaker:levitate in whatever area that you have. We have a
Speaker:vacuum system. We push atoms inside like
Speaker:evaporate atoms to the vacuum system and
Speaker:then shoot the laser to the atom. A bunch of Atom 10
Speaker:to 2010 to power 20 like and then ionize
Speaker:atoms send electron out will be ion. And the
Speaker:ion, because it has a charge, you
Speaker:can trap it with the DC and RF voltage. And
Speaker:then that trap is very deep. Compared to the neutral
Speaker:atoms. Neutral atoms is shallower. Like if
Speaker:you some other hydrogen atom inside your vacuum
Speaker:system come and hit the atom can kick
Speaker:it out. But in ion trap is deeper. Like you
Speaker:need more energy to kick it out than if you trap
Speaker:like one ion in your vacuum system. You can have it
Speaker:quite long for a day or two and then do the experiment with it.
Speaker:Compared to neutral atom which is like quickly will
Speaker:escape and you need to trap it again and again. But
Speaker:in terms of the physics they are quite similar. Like the way that we
Speaker:trap is different. But in terms of physics you can find a lot of
Speaker:similarity. Yeah. Compared to the
Speaker:superconducting cube. Superconducting qubits are circuits.
Speaker:Like in principles are electronic circuits
Speaker:in the quantum level. Like they have some non linear component.
Speaker:Like in the normal electric circuit we have
Speaker:rcl. But they have some component which is
Speaker:non linear. And they can work as the source of
Speaker:making the energy differences and make a qubit. They
Speaker:are handmade compared to the atoms which is
Speaker:natural. Like it's very
Speaker:difficult to make 10 quantum bit in
Speaker:superconducting qubits similar. Exactly. Because
Speaker:it's handling. But in in atomic word they
Speaker:are similar in nature. In. In that sense it's easier
Speaker:to to start with. But the
Speaker:difficulty will come afterwards when the engineering comes. Like
Speaker:the electronics supports a lot the
Speaker:superconducting cubits back in AD 19. Then
Speaker:there's a huge engineer development there which is
Speaker:missing in atoms and ion community.
Speaker:If we could fill that gap, they could
Speaker:outperform the superconducting qubit because
Speaker:naturally their properties are better.
Speaker:That's the differences between these two. Like a
Speaker:way of or three photons, superconducting
Speaker:qubits and atom or ion base.
Speaker:Okay. So there's a lot of precision that goes behind
Speaker:the ion traps. It's very exciting. You get lasers,
Speaker:vacuum chambers, electromagnetic fields,
Speaker:all these mind blowing ideas all working
Speaker:in Harmony. What's the most challenging part
Speaker:of building or maintaining an ion trap system
Speaker:at the moment? Scalability. That's the,
Speaker:that's the, that's the challenging part. The
Speaker:rest is already is manageable. Like you can have
Speaker:recently Quantinium published like a 98 qubit.
Speaker:And with the benchmarking, when I say
Speaker:there is some spec of your machine that will define
Speaker:how it's working in terms
Speaker:of the element level and in terms of system level.
Speaker:There's a huge people that working on this benchmarking
Speaker:different machine. And
Speaker:what was, what was the question? I forgot I was saying what was the most
Speaker:difficult. The difficult like the scalability. Then you want to increase
Speaker:this like a 98 qubit to 500 or thousand
Speaker:or 10,000 or 30,000. How you want to do that?
Speaker:That's challenging. Like different
Speaker:architectures already like is
Speaker:under investigation to see how we can do that.
Speaker:Yeah, two main way to do for the ion trap
Speaker:is either do it like a
Speaker:node base, like have 100 qubit here,
Speaker:100 qubit somewhere else like within like
Speaker:acceptable range and then connect them with photons. Then that
Speaker:way you can extend and escape.
Speaker:That's one approach that IonQ and IX or
Speaker:Linux recently starting that kind of approach. And
Speaker:also another approach is it's called qccd.
Speaker:You have core center and then you transfer
Speaker:physically or ion to somewhere else and do something and bring it
Speaker:back like transferring between different nodes
Speaker:that you have. That's also another approach that
Speaker:some company is using that approach to
Speaker:reach to scalability. But still it's very difficult challenge
Speaker:to overcome. And like a company put
Speaker:like a 32,000, 2030 or
Speaker:2035 to reach to some level of 30K
Speaker:level of scalability like number
Speaker:of the qubit that you have plus the rate of error that you
Speaker:have each single qubit. So do you think the
Speaker:trapped ion systems will eventually power
Speaker:commercial quantum computers or are they more likely to
Speaker:remain like the gold standard for scientific
Speaker:precision and benchmarking? Yeah, it's a
Speaker:difficult question, but the paper publication that
Speaker:you could already see in
Speaker:terms of system benchmarking.
Speaker:Like system benchmarking means that you have some specific
Speaker:algorithm and you give it to me, I will run it on
Speaker:ion trap machine. You give it to the second ion trap
Speaker:machine, you give it to the neutral atoms machine, you give it to the
Speaker:photonics machine, superconducting machine and compare the result
Speaker:in terms of accuracy and the time that it takes
Speaker:to get back the data.
Speaker:Like iron trap, it's top now like with the
Speaker:error rate and Even with the lower number of the
Speaker:qubit compared to, for example, superconducting. But
Speaker:in terms of the overall, like a benchmarking is still. Yeah, it's
Speaker:better than superconducting.
Speaker:But this question. Yeah, it's very difficult to
Speaker:answer. There's like some other competitor, like a photonic base.
Speaker:They're claiming for a million qubit, but it's not out there
Speaker:yet. Right, but it could come, like, who knows?
Speaker:Yeah, so. So are sheer number of
Speaker:qubits going to matter or is it logical qubits and there's physical qubits.
Speaker:Like is. Is there? I think what I really want to know is like, what
Speaker:trapped ions, you know, the dealing is good for one type of problem
Speaker:photonics are good for. Where does trapped ion really, like,
Speaker:shine? Like, the original question that
Speaker:you mentioned was about the logical and physical qubit. Well, yeah, I know.
Speaker:I. Sorry, I had way too much coffee, so I dumped a couple of questions
Speaker:on you. Sorry about that.
Speaker:But the first question I want to ask,
Speaker:let's hit the undo button on that.
Speaker:Trapped ions, where. What problems are
Speaker:they really perfect for? Is really the question I want to know. Like,
Speaker:where. You know, if I'm looking at a whole suite of problems,
Speaker:kneeling is good for one type of thing, photonics. And where does.
Speaker:Where does trapped ion really excel? Because, yeah, I think the target
Speaker:for trap ion is the universal quantum computation. It's not just
Speaker:any gotcha. Okay. It's like, yeah, in any
Speaker:algorithm that you can give it and get the answer, it's a matter
Speaker:of like quantum volume, like a number of a qubit, error
Speaker:rate, those kind of things. But the target is to solve
Speaker:like a hard problem that the classical computer cannot. That. That's the
Speaker:target. Gotcha.
Speaker:Yeah. Because I can easily see like, you know, kind of. I'm old enough to
Speaker:remember the, the early, like WINTEL days where like this is 100
Speaker:megahertz, this is 150 megahertz, this is 166 megahertz.
Speaker:Right. You know, like that, like that became like a marketing scheme.
Speaker:Like, and I know that there was a hard. There was a speed boost attached
Speaker:to that, but yeah, beyond a certain point, it was not really a
Speaker:meaningful measure of how fast the machine is.
Speaker:And it seems to me that quantum, like number of qubits and all the.
Speaker:That's even more complicated. And number of qubits does not
Speaker:necessarily mean number of logical qubits.
Speaker:So it seems like how you know, at some
Speaker:point when this becomes real, real, real and not that it's
Speaker:not real. Today. But when it becomes something that you know you'll see ads for,
Speaker:how are they going to be measured? Like how do you compare one quantum computer
Speaker:to another? Like you know, that was, that was the question. Actually Kendence
Speaker:mentioned that benchmarking has a several different
Speaker:like layer, right? Benchmark different like
Speaker:component level and say okay, I do one
Speaker:gate, two gate and the spam detection with this much
Speaker:error. That's very good. But it's not the whole
Speaker:story. The whole story is that you give me a like
Speaker:a sample algorithm, that it's a standard algorithm and then
Speaker:you can run it on classical machine and see, okay, takes 10 to
Speaker:25 years to be solved and then run it on like a quantum
Speaker:computer and then see how long it takes
Speaker:and how accurate the result is and then compared
Speaker:with the other machine. Like this type of benchmarking is already
Speaker:is ongoing. Like a lot of
Speaker:quantum machine that is out there. They are
Speaker:publishing based on that kind of like they're trying to
Speaker:publish several algorithms. 1, 2, 3 and the paper and saying okay,
Speaker:we did this on this machine and then this is the result.
Speaker:And then even they compare it with some other machine back to back then
Speaker:show the result how like how much
Speaker:error with how much uncertainty you can give this
Speaker:answer those kind of measure is a more
Speaker:system level benchmarking. That's more important
Speaker:at the end of story. I gotcha. All right, that makes
Speaker:sense. So for students or engineers who are
Speaker:fascinated by trapped ions,
Speaker:what skills or areas of study would you
Speaker:recommend they start exploring now?
Speaker:Definitely start with physics background and AML physics,
Speaker:atomic and molecular physics. That's the
Speaker:core for
Speaker:understanding the single ingredient
Speaker:inside. But at the moment we need a lot of
Speaker:other skills need to be developed also like optical
Speaker:engineer. Like we need to
Speaker:take the data from atoms or ions to
Speaker:our detector and then we need some collection
Speaker:system and imaging system for example. That's very important.
Speaker:Understanding laser, how we can use the laser,
Speaker:how like we can control the different spec of the light.
Speaker:That's very important. And either
Speaker:mechanical engineer comes with the game because you need
Speaker:to make like here at oqd
Speaker:every time we hire several co op students that we have
Speaker:in here in Canada that the students in the bachelor level in
Speaker:mechanical engineer should come to some company and learn for
Speaker:something for for like a four months and they have to be
Speaker:paid also they come to this machine and then they helps us
Speaker:to build some optomechanical modules
Speaker:that we need to make it with specific spec
Speaker:to build our whole machine. That's also
Speaker:important. It's not to the core of the like iron
Speaker:trap, but it's very super critical
Speaker:to, to, to show the criticality of this
Speaker:like making mechanical stable system. Like we
Speaker:have 30 ions sitting 4 micrometer
Speaker:beside each other, like 120 micron. And
Speaker:then this is the, like a line of the ions that we start
Speaker:working and, and doing quantum computation with them.
Speaker:Like the thickness of the hair, human hair, is 100 micron.
Speaker:Like this, like a string is sitting at the cut of the human
Speaker:hair. And then you need to control each
Speaker:individual atoms with lasers.
Speaker:And then the laser that you're talking with atom number one
Speaker:shouldn't talk to, with atom number two. You shouldn't have crosstalk
Speaker:like four micrometer away and
Speaker:four micrometer away. And then you can imagine
Speaker:how stable your mechanical system needs to be
Speaker:to not make these two mixing each other.
Speaker:And it become very important indirectly to
Speaker:the main problem. But for people who are interested
Speaker:as a builder or as a user, two different categories.
Speaker:Builders are the people who should know about the
Speaker:atomic physics, this laser, optical engineering,
Speaker:mechanical electrical users.
Speaker:They should know more about the software because like whenever that
Speaker:you use your classical computer, you don't ask about like how the CPU
Speaker:is built. The software level,
Speaker:like more theoretical physics will be the user. Like
Speaker:the comparison will be builder of telescope and user of the
Speaker:telescope. Like there's like a two different category and we are in the builder
Speaker:side of open quantum design. We are building the,
Speaker:the machine. And then some people coming from
Speaker:theoretical physics can come and use it afterwards.
Speaker:That makes sense.
Speaker:That makes sense.
Speaker:What's the most surprising or beautiful thing
Speaker:you've ever seen happen when working in a quantum
Speaker:experiment?
Speaker:Yeah, like you see some unexpected effect
Speaker:and you see that kind of noise and then after some
Speaker:investigation you see that, oh, that's another phenomena that it's
Speaker:kind of coming to your game and showing and it,
Speaker:yeah. Then go to the theory and see, oh, that's, that's kind of interesting things
Speaker:to develop. Even sometimes you will be
Speaker:sidetracked to that kind of problem and see some
Speaker:achievement happen at that kind of noise that you saw in the system.
Speaker:I've seen several of these examples on my
Speaker:own research. It's kind of very super
Speaker:interesting and exciting. Yeah, I also wonder too,
Speaker:like, you know, how much, how much of it is you get this, like, is
Speaker:that, wait, is my equipment like messed up or is my seeing a new
Speaker:undocumented phenomena? Right. Like, you know. Yeah, yeah, yeah. There's probably a bit of
Speaker:excitement, a little bit of skepticism and a little bit of like you know,
Speaker:not sure which it is. Yeah, that's very important in
Speaker:the AMO physics lab. One of the differences that I would
Speaker:I should highlight here is that in. If
Speaker:have you ever been in like a experimental lab, like AMO
Speaker:lab? I have not, no. No, it's. It's kind
Speaker:of very super messy. Everything like the
Speaker:cables coming, lasers and the mechanics. And then
Speaker:in principle that system works just once and then paper
Speaker:published and then second time you don't know that it's working or not. You need
Speaker:to spend a little time to like in principle students
Speaker:spend like a 90% of the time to fix the problems
Speaker:ongoing and then probably 10% doing a real
Speaker:experiment on a normal like
Speaker:AMLABS. One of the goal of the OQD
Speaker:is that change this ratio to lower value.
Speaker:Try to make the system more stable and more modular
Speaker:in the way that we can monitor different sections
Speaker:and also make it stable
Speaker:overall working for a long time. More
Speaker:work as a commercial product compared to the R and D product.
Speaker:The comparison will be like a breadboard in electronics and then the
Speaker:PCB version, like breadboard is the time that you do
Speaker:testing and then PCB is like a solid.
Speaker:And yeah, in OQD we try to go from
Speaker:like a breadboard version, messy version to more solid and
Speaker:PCB type version and try to change its
Speaker:balance. Like spend less time on fixing problems, spend more time
Speaker:on doing the experiment. Actually that's
Speaker:one of the main goal here. And we could see like we have another lab
Speaker:design, the OQD that is R and D based in
Speaker:the grandpa of our lab. And we could see
Speaker:the thing that they spend like a year to achieve. We
Speaker:could do it in like two weeks.
Speaker:That's very, very distinct value that
Speaker:you could see. We have a lot of camera photodiode in our system, probably plus
Speaker:hundred that monitor different level of the system
Speaker:and report the errors. And that will
Speaker:help you to maintain the system commercially.
Speaker:Not. Not as a physicist, it's a more engineer.
Speaker:Okay, interesting. So there's a
Speaker:lot of kind of interdisciplinary collaboration that's
Speaker:happening exactly in quantum development. Right. You've got your physicists,
Speaker:you've got your engineers, computer scientists. So how
Speaker:do you, how do you find the shared
Speaker:language so that you're able to kind of bridge those
Speaker:disciplines effectively? Yeah, Someone
Speaker:who has like a little bit of each one of those needs
Speaker:should be on top of the project. Like should lead everything.
Speaker:Like a person who knows a little bit software, mechanical
Speaker:optics should be on top of that too.
Speaker:Whenever that you hire someone from a Specific vision
Speaker:can get benefit of his experts knowledge out.
Speaker:Yeah, that's very crucial to have someone who has
Speaker:done a little bit on some of those kind of activities.
Speaker:Okay.
Speaker:Yeah. For people who probably trust that you can later
Speaker:put like open Quantum design Link and also GitHub
Speaker:to the people who are interested to see what kind
Speaker:of things already it's on public level that everyone can
Speaker:see on hardware and software. We have also some
Speaker:simulation level which is very important also from aim of physics
Speaker:simulation that anyone who want to run
Speaker:anything can use that from our GitHub and this
Speaker:GitHub will be more and more published in future
Speaker:whenever that we get some spec of our prototype
Speaker:and then they could have more information of each
Speaker:individual module that we have here.
Speaker:Interesting. Yeah, I think there's a lot, there's a lot to say.
Speaker:Like you know, it seems like quantum computing
Speaker:is going to need a lot of multidisciplinary and
Speaker:people. So I think would that be good advice for people like if you're really
Speaker:good at one thing, learn a little bit of something else. Yeah, yeah. And
Speaker:actually I think from the report in the
Speaker:North America I've heard some, I've seen some like a
Speaker:publication that there is shortage on the workforce
Speaker:for quantum development.
Speaker:That's interesting. And that coming, that's coming from
Speaker:different kind of principles. As I mentioned
Speaker:it could be completely not relevant to
Speaker:the. To the quantum word, but it's directly
Speaker:relevant to building the quantum computer. Right.
Speaker:So how close are we really to seeing
Speaker:quantum technologies like quantum memory
Speaker:or quantum Internet change our everyday
Speaker:lives? Yeah,
Speaker:I think we like a quantum related phenomena
Speaker:is already affect our life. Like whenever that
Speaker:you are using gps, you're using atomic clock.
Speaker:That's definitely direct use of
Speaker:the quantum word in daily application. If it
Speaker:comes to the quantum memory also
Speaker:my PhD was on the quantum memory based. There are already some
Speaker:companies that building quantum memory and quantum
Speaker:repeaters across the world testing across
Speaker:like a hundred fiber, 100 kilometer fiber and.
Speaker:And that will be crucial also for future
Speaker:quantum like a cryptography or for quantum
Speaker:computing even like some, some company already doing
Speaker:that. And for quantum computing it's a little
Speaker:bit further out. Like
Speaker:quantum memory, quantum communication, quantum sensor is closer
Speaker:and you have some product already. But quantum computing it's a little
Speaker:bit back and still we're not there to say
Speaker:this is directly used on our daily lives. But
Speaker:some problems like finding the proper drug
Speaker:for example, that's one of the things that
Speaker:the quantum computer can affect.
Speaker:If you have a quantum computer easily can break
Speaker:your cryptography that you have for
Speaker:bank account these days. That's a thread to
Speaker:a daily life if it comes to the reality.
Speaker:And that's already has a lot of people on it.
Speaker:Yeah, yeah. That also could be something that
Speaker:yeah. Will affect.
Speaker:Yeah. But yeah, it's a very tough question to say
Speaker:exactly what, what will be there? Who knows?
Speaker:That's fair. That's fair. I always like to, I ask this question in every
Speaker:single interview and I always love the answers.
Speaker:How would you explain what you do
Speaker:on a daily basis to a non technical person who's not in
Speaker:your field, like just completely non technical. How can you explain
Speaker:it and break it down?
Speaker:You mean what in terms of what. In terms of like
Speaker:in terms of what, what you're doing in quantum computing. In terms of what
Speaker:you're, what problems you're trying to solve. Is this the
Speaker:cocktail question? Kind of, yes. Things like, you know,
Speaker:like if you're at a cocktail party or whatever and what do you do? Well.
Speaker:How do you break it down? How do you unpack it a little bit.
Speaker:For like explain. Like I didn't fully get probably the
Speaker:question that explaining the, the problem that I'm working
Speaker:with in or in general, like a quantum computation.
Speaker:Which one? I would say in general. Yeah, you get the question
Speaker:what do you do? Right. And you have to assume they're a civilian,
Speaker:right? Like they're not. Yeah, yeah,
Speaker:yeah. I could go like, I could say like for example, if
Speaker:you go to the, to the beach and get one of those
Speaker:tiny sand on the beach that
Speaker:has 10 to the power of 20 atoms inside
Speaker:one of those tiny sands and here
Speaker:we are working with one single atoms.
Speaker:Wow.
Speaker:That probably can bring you
Speaker:in the scale size. How
Speaker:difficult is to work with this guy
Speaker:in terms of the scale of your system control? For
Speaker:example, if you consider Toronto to London, for
Speaker:example, you want to report the distance
Speaker:between these two cities by nanometer scale.
Speaker:That's also in terms of scaling factor
Speaker:for controlling your laser light, whatever that you do that you want to control this
Speaker:single atoms, you need to have that kind of control. And we have
Speaker:that kind of control that we can report the distance between
Speaker:New York, London with nanometer scale.
Speaker:Then you can go to your cocktail party and think about this kind of
Speaker:things.
Speaker:We have a lot of folks who are, you know, who are
Speaker:currently, they're, they're physicists, they're really in academia
Speaker:and they want to grow over the bridge into industry
Speaker:where you are now. And they don't necessarily know how to navigate
Speaker:that transition. Is there anything that you
Speaker:could talk about in relation to that, the transition you took.
Speaker:Yeah, the industry is. Yeah. As you know, it's
Speaker:completely different world compared to the academia
Speaker:or going towards that direction, like improving the
Speaker:skill set of like a
Speaker:daily activity and close some small like
Speaker:task that's very crucial for, for
Speaker:industrial level activity compared to the academia. The
Speaker:academia is more like a long term plan working on something for
Speaker:very long term. But in industry you need to deliver
Speaker:something on some specific day and that
Speaker:makes you like decide differently.
Speaker:Probably your system that you want to close, it is not perfect, but it can
Speaker:do the job that you want to do for that specific task.
Speaker:That kind of, in terms of the mind level, you
Speaker:need to change your mind from like very
Speaker:optimized for the best system that you want to make
Speaker:it to the system that it worked for that specific task.
Speaker:And whenever that task finished, then the second
Speaker:task can like improve that third task can improve
Speaker:that and then you, you will reach to the final goal but in different
Speaker:way. In industry. Yeah. You have some
Speaker:commitment to deliver some result in, in a team,
Speaker:in a big team, like a 40, 50 people, hundred people,
Speaker:they want to accomplish some, some goal
Speaker:and that's, that's very important to do your task
Speaker:on some specific tool like task
Speaker:at deadline.
Speaker:Interesting.
Speaker:Any other further questions? I know we're getting close to the top of the hour
Speaker:and. Well, I've asked my favorite cocktail question. I know, I
Speaker:know. That is my favorite one. I love doing that.
Speaker:But it does force somebody to kind of explain. Right. Like, and I
Speaker:think that's also going to be an important skill going forward for anyone in
Speaker:academia. Like you can't assume that people even know. Like
Speaker:you said 10 to the 20th power of. You can't
Speaker:assume that anyone would know. What that even means. Right. Like,
Speaker:you know, but no, I
Speaker:mean that's important. Right. Because you know, at some point if you do want to
Speaker:make that bridge, you do, you're going to have to stand in front of an
Speaker:investor in some of the, in front of a customer. You kind of have to
Speaker:explain like what this is. Right. And you know,
Speaker:that's, that's. I think that's a challenge. Every technologist, regardless
Speaker:whether it's quantum physics, whether it's AI, whether it's, you know. Yeah.
Speaker:You know, has to come across. Right. The, the person, the hippo, which I don't
Speaker:know if you've heard that acronym before. Yeah. Have I used that acronym in front
Speaker:of you, Candace? Yes, I've heard it. It's one of, it's one of Your favorite
Speaker:ones. Also NIMBY is your other one that you. Yes,
Speaker:yes. So hippo. Not my bad. Backyard. I've learned that one.
Speaker:Tell them the hippo. You know, have you heard the Hippo? The hippo acronym?
Speaker:Yeah. Highest paid person's opinion. Yeah, I, I first
Speaker:heard it at Microsoft and somebody was like, well, you know, doesn't really
Speaker:not going to name who that hippo was, but that was, that was pretty interesting.
Speaker:You know, it was like hippo, like. And my, my mind went immediately
Speaker:to hungry, hungry Hippos. And then it was like, no, no, no. This means like
Speaker:highest paid persons. But you mean the highest paid person in any
Speaker:given enterprise is probably not going to have a
Speaker:background in quantum physics, right? Yeah, I think that's a safe
Speaker:assumption. Could be wrong. But again, you know,
Speaker:but yes, you have to. The people cutting the checks or, you know, you have
Speaker:to, you have to convince them that you're a startup, the value of
Speaker:it before they write that check. Um, and I
Speaker:think that this is something that, you know, this is
Speaker:what separates kind of like the famous entrepreneurs in
Speaker:tech from the ones who are not. Right. Like, you know, Steve Jobs,
Speaker:you know, was he the most
Speaker:proficient software engineer or computer builder? Probably not.
Speaker:That was probably Woz. Steve Wozniak. But what he could
Speaker:do is sell vision, sell the end result. Yeah, I think that's really,
Speaker:that's where the magic is, right? Yeah, this is the same like in
Speaker:academia world you have some Prof. Which
Speaker:is very, very knowledgeable, but they're not good at teaching
Speaker:and vice versa. This is the same thing in industry,
Speaker:like presenting idea and compared
Speaker:to the knowing knowledge deep of that kind of area.
Speaker:The same thing we have in academic also, like. Yeah.
Speaker:Well, I think that's, I think that's a good, a good point to, to
Speaker:leave us off on. I think that we've asked some really good questions
Speaker:today. I've loved everything we've been talking about. We really haven't
Speaker:had someone who's been able to focus on trapped ion for us before.
Speaker:So that is very exciting for us. Yeah,
Speaker:that really is. Because like, I know that's one of the core. That's one of
Speaker:the oldest, like, so like it's, it's something that like it's can't be
Speaker:ignored and we've kind of ignored it up till now. So.
Speaker:Yeah, great. That, I mean, that was a good
Speaker:opportunity to talk to you. And
Speaker:also I heard about the other podcast during the last
Speaker:couple of days. That was also interesting too. Thank you. Yep.
Speaker:Thank you. Thank you. Thanks for joining us. On impact Quantum
Speaker:Today's deep dive into. Trapped ion hardware showed just how precise. And
Speaker:powerful this technology can be. If you enjoyed this episode,
Speaker:subscribe and stay curious. More conversations at the
Speaker:cutting edge of. Quantum tech are on the way.
