Announcing the D-Wave 2X

We are very excited to announce the general availability of the latest generation of D-Wave quantum computers, the D-Wave 2X™ system.  With 1000+ qubits and many other technological advancements, the D-Wave 2X will enable customers to run much larger, more complex problems on the system.

Here is a press release describing the system, and here is a paper describing benchmarking results performed on it.

Here is one, in the Burnaby lab.

  1. Hi Geordie: I have one simple question, and it’s this: Since the chip is an array of 16x16x8 for a total of 2048 qubits, I don’t understand why the whole chip(all 2048 qubits) isn’t calibrated and utilized in computations? Aren’t there advantages to using all of the functional qubits in the new chip vs. about half of them? Pardon my ignorance! At any rate, keep forging ahead. Wish the whole team nothing but great success. This is great news. Thanks & best of luck.

    • The analog nature of our processors means there is a spread in parameters across the processor area that plays a key role in performance. For the D-Wave 2X product we focused our effort on tuning this parametric spread on the smaller 1,152 qubit sub-graph of the larger processor, and this enabled significantly better performance. A key piece of our technology effort now is maximizing performance over a much larger processor area and we plan on releasing that in a 2000Q processor release next year.

  2. Hi Geordie: Here is an objective article, from Ars Technica, about your latest benchmarking test results that were released recently. The writer is a Ph.D. physicist who has written extensively on D-Wave in the past. You might want to include it in your “Media News” section. Thanks and good luck.

    • There are several generative algorithms that could be used to produce visually interesting output. An example is the handwriting generation that Alex Graves did with LSTM type models. You need to modify these to fit with the D-Wave computing constraints but this could certainly be done.

  3. Hi Geordie,

    Just heard about the BIG Sale of Dwave 2X to Los Alamos Labs! Congrats! Finally some exciting news!🙂

    Is it possible to install multiple or parallel Dwave processors in a single fridge? I was wondering if the processor is already doing parallel computing, is there still a need for multiple processors? Just curious🙂

    • Hi Ramsey, thanks!!! It is possible to put a lot of processors in one fridge — potentially a huge number. They don’t generate much heat, and since the marginal cost of fabricating more processors is essentially zero we could put thousands / millions of processors per fridge before running into physics I think. The reason we keep putting this off is that the engineering effort is substantial and the team is too small to take this on in parallel with the central “Rose’s Law” scaling, and if we have to choose between upgrading the single processor and parallelizing the ones we’ve got, currently the first one is the preferred strategy.

      • Wow! I didn’t expect you can stuff that many processors in the fridge, that must pack a lot of processing power! By the way, kudos to another achievement on the 100 million times faster than simulated annealing benchmark by Google. Excellent engineering on the 2X.

        I thought Hartmut Neven mentioned a plan to increase the density of the D-Wave processor. Is it anywhere near the density or miniaturization of today’s desktop PCs processors, like Intel Core 14nm processors?

      • Hi Ramsey! The areal density of the processors is limited by fabrication technology. As the fabrication technology improves, what you can do on the design side grows. Right now the current processors have on the order of 100,000 Josephson junctions, still a long way from modern VLSI in terms of device count. When planning for future processor architectures, the input of our customers, such as Google, is taken into account. However ultimately we make these types of decision based on a multitude of factors. Building this type of computer system is a complicated business, and design decisions always involve trade-offs and rarely is the naive answer the correct one.

  4. Hi Geordie,

    2 simple questions.
    1) I am not a religious person but I do fear that the progress of AI could put humanity in danger with the recent developement of robotics, especially with the new darpa humanoid model…What is the point of view of your company in these matters?

    2) What kind of language is used to program directly the d-wave computers…Not the language that are used by external customers but the language your technicians use to code the d-wave cpu.

    Thank you

    • Hi Jean Philippe, re. 1 — the role of AI in the future is complex but I believe it will turn out to enable abundance and flourishing on a scale never before seen. Re. 2, the language closest to bare metal is LISP.
