[5:01:09 PM] Mind says: A very warm welcom to our esteemed geust Dr. Geordie Rose of D-Wave Systems
[5:01:18 PM] Geordie Rose says: Thanks for having me.
[5:01:28 PM] Mind says: First of all I realize there may be some proprietary information that you cannot discuss in this chat, so if a question comes up that you are not at liberty to discuss, please just say so and everyone will understand.
[5:01:38 PM] Geordie Rose says: OK.
[5:01:50 PM] Mind says: Secondly I want congratulate D-Wave on its successful demonstration in 2007 and hope for similar success in 2008.
[5:02:01 PM] Geordie Rose says: Thanks!
[5:02:04 PM] Mind says: Before I get into the questions I want to again confirm that D-Wave has succesfully garnered another round of funding.
[5:02:13 PM] Geordie Rose says: Yes, we just closed another $17M as of last Friday.
[5:02:26 PM] Mind says: Also, near the end of 2007, D-wave issued a press release claiming to be on pace to demostrate a 512 qbit computer by the 2nd quarter of 2008, and a 1024 qbit computer by the 4th quarter of 2008. Are you still on that trajectory?
[5:02:34 PM] Geordie Rose says: Yes, there are still issues with transitioning to a fully scalable architecture but we’re confident we can pull it off.
[5:03:11 PM] Mind says: Many skeptics said they will reserve judgement until they see a functional 1024 qbit computer. Do you think they will come around once a 512 qbit computer is released, or hold off until 1024
[5:04:33 PM] Geordie Rose says: Once the system is sufficiently large (about 100-200 qubits) there are "smoking gun" tests that the processor is a quantum computer. So even before 500 qubits the issue will be settled.
[5:05:32 PM] Mind says: So the "smoking gun" will arrive before you have a working 512 qbit computer?
[5:07:25 PM] Geordie Rose says: We're planning to go directly to 500+ qubits once the architecture becomes fully scalable. There's no good reason to aim lower, but there is a good reason to set this as the objective (having to do with testing new I/O systems).
[5:07:49 PM] Mind says: What about commercial prospects. I realize the main thing being talked about is a quantum computer's ability break current encryption with ease. What else do you foresee?
[5:08:04 PM] Geordie Rose says: The system is architected as an accelerator for a type of problem called quadratic binary optimization problems (QUBOs). Many important problems can be mapped to QUBOs. My main areas of interest are life sciences (bioinformatics) and synthetic intelligence (pattern matching, machine learning).
[5:08:22 PM] Geordie Rose says: as for factoring, it's an interesting and important application. We'll be thinking about it.
[5:10:05 PM] Mind says: Imminst members are particularly interested in the life sciences aspect? When you talk about bioinformatics can you give a concrete example of something that is being done with classical computers that will be much better suited to a quantum machine.
[5:10:19 PM] Mind says: Whole body simulation?
[5:10:28 PM] Mind says: Database searching?
[5:13:16 PM] Geordie Rose says: It principle anything that involves discrete variables (like amino acids or elements of a systems biology network) and something combinatorial, like searching to find some optimum. Examples include protein folding, multiple sequence alignment, creation of philogenetic trees, lots more. Whole body (or just the brain) simulation is very interesting to me. For example neural nets are closely related to our hardware. Also extraction of complex relational information from databases is also something we're working on. Related to memory in neural nets.
[5:13:55 PM] Mind says: I see you also mentioned synthetic intelligence. Do you think quantum computation is a necessary component for AGI?
[5:14:11 PM] Mind says: I know Ben Goertzel thinks we can get there fairly soon with classical computation.
[5:14:50 PM] Geordie Rose says: The short answer is no, I don't think QC is required. However I do think that QCs can do the computations that underlie AGI more efficiently than classical methods.
[5:15:18 PM] Mind says: Ok, at this point I would like to solicit questions from the audience
[5:15:30 PM] Mind says: feel free to jump in with anything new
[5:15:43 PM] Mind says: or any follow-ups to what has been said so far.
[5:15:49 PM] Paul Carver Tiffany III says: how scalable do you expect to be past 1024 qbits? Are you intending to sell to a larger company (IBM)? If not, do you plan on renting out qbits forever, or do you see yourself selling hardware eventually?
[5:17:42 PM] Bryan Bishop says: Are there any public "quantum" APIs for programmers interested in getting a head start in thinking like a quantum programmer?
[5:17:47 PM] Geordie Rose says: I can see the current approach scaling to about a million qubits. The reason we can't go to the levels of integration of cmos/mram is that the qubits have to be fairly large in our approach. We are building the company to be around for a long time, we have no plans to sell to anybody. We do plan to place hardware remotely--how this will work from the business side might not involve sales.
[5:18:21 PM] Geordie Rose says: kansuze--yes, we do have APIs and they are available now for C, java and matlab.
[5:18:36 PM] Bryan Bishop says: You will remotely host the quantum computers? How would we know that they are then truly quantum? Walk-throughs of the facilities?
[5:18:46 PM] James Clement says: Can you put 1024 qbit processing in perspective for those of us who might not readily be able to visualize the difference? For example protein folding on a fast computer, versus the 1024 qbit?
[5:19:58 PM] Geordie Rose says: Kanzure--yes the facilities can be inspected. Also over time benchmarks and such will be published and it will become less shocking that QCs exist. I think it's shocking that they don't yet.
[5:21:08 PM] cnorwood says: Dr. Rose. If someone wanted to research Quantum Information Theory, what college path should they take? Physics, Computer Science, Math?
[5:21:32 PM] Geordie Rose says: James--it isn't always easy to make a straightforward statement about capability as a fucntion of qubits. Depends on a lot of things, the most important of which is the skill of the programmer. 1024 qubits can in principle hold 2^1024 simultaneous states but there are some real tough issues in using this sort of power, and sometimes you can prove you can't!
[5:22:37 PM] Geordie Rose says: cnorwood--any of those would work. I did engineering physics and then physics in grad school. I personally think physics is the best because ultimately the machines have to be made out of stuff and this fact can be abstracted away if you think too much like a mathematician!
[5:23:06 PM] cnorwood says: thanks!
[5:23:22 PM] calyban8 says: how do you keep them cold?
[5:23:35 PM] Bryan Bishop says: vacuum?
[5:23:51 PM] Geordie Rose says: dilution refridgerators. 5 millikelvin. about 500 times colder than interstellar space.
[5:24:28 PM] Mind says: You mentioned some scaling difficulties. Are these just basic engineering problems? Or is it something with the theory of the design?
[5:28:03 PM] Geordie Rose says: There are both engineering issues (although the semiconductor industry has solved most of these already) and basic physics issues (mostly related to noise).
[5:28:20 PM] Mind says: Are you aware of any other quantum computers around the world that are ready for commercialization (or at least near), whether in private industry or through government efforts?
[5:29:00 PM] Geordie Rose says: Unfortunately no-one but us is really trying, at least in the public domain. So no.
[5:29:38 PM] Bryan Bishop says: Are you going to be making a quantum computing cluster ?
[5:30:26 PM] Geordie Rose says: bryan--we already have one! The way our lab is set up all the machines are accessible through the same interface and can be run as parallel processors.
[5:31:01 PM] Mind says: A brilliant physicist friend of mine remarked that proving it works is only the first step to widespread utilization. Profitibility is sometimes a hurdle. Are you fairly certain that the applications of D-Wave quantum computers will be obvious commercial successes right out of the gate?
[5:32:19 PM] Geordie Rose says: It really depends on how quickly the hardware can be scaled. I think the answer is most definitely YES with a million qubits. So I am pushing to get to something at that scale as quickly as we can.
[5:32:36 PM] Mind says: OK, we have reached past the 30 minute mark and Dr. Rose has a flight to catch so last call for one more question.
[5:33:15 PM] Mind says: Anything else you would like to mention Geordie?
[5:33:52 PM] Geordie Rose says: Just that I appreciate the opportunity. I have been thinking about "uploading" for a while now... maybe I'll do that after we solve the QC problem
[5:34:35 PM] Mind says: One more question from James
[5:35:25 PM] James Clement says: Thanks Dr. Rose. I'd invite you to check out www.innerspacefoundation.org regarding a neuroengineering approach to uploading and other issues.
[5:35:52 PM] Geordie Rose says: Cool thanks for the link. I'll check it out. Thanks everybody, fight the good fight.
[5:36:07 PM] Mind says: A very big thanks to Dr. Rose for sharing the latest in the quantum computing scene.
[5:36:15 PM] Mind says: It was very enlightening
[5:36:27 PM] Mind says: I wish you and D-Wave much success in the coming year
