Google and NASA Snap Up D-Wave Quantum Computer 108

Posted by Unknown Lamer from the at-least-we-think-they-did dept.
ananyo writes "D-Wave, the small company that sells the world's only commercial quantum computer, has just bagged an impressive new customer: a collaboration between Google, NASA and the non-profit Universities Space Research Association. The three organizations have joined forces to install a D-Wave Two, the computer company's latest model, in a facility launched by the collaboration — the Quantum Artificial Intelligence Lab at NASA's Ames Research Center. The lab will explore areas such as machine learning — useful for functions such as language translation, image searches and voice-command recognition. The Google-led collaboration is only the second customer to buy computer from D-Wave — Lockheed Martin was the first."

          In many cases, practicality does trump elegance. But in many other cases, it does not. For a mathematician, some problems -- like the TSP -- are interesting precisely because we don't know (P=NP?) if the only practical approach we have for solving them is inelegant brute force. Factorization of large integers is another one of those interesting problems (you alluded to it as "prime generation.") The existence of an elegant solution to the factorization problem would considerably alter how we conduct secu

    From a recent Financial Post article profiling D-Wave:

            If computers could learn, grow and evolve the same way humans can, the world would be a much better place, Dr. Geordie Rose argues. The co-founder and chief technology officer of Burnaby, B.C.-based quantum computing firm D-Wave Systems Inc. contends that humanity would gain unprecedented access to education, health care and information if only his company’s technology were more widely adopted. Having sold its first quantum computing system to Lockheed Martin Corp. for approximately $10-million, the doctor of theoretical physics spoke to Financial Post technology reporter Jameson Berkow about his plan to change the world. The following is an edited transcription of their conversation.

        If that's their intent, they'll be sorely disappointed, since D-Wave's machine has only 512 qubits (where as all new SSL certificates are at least 1024 bits). More importantly, the machine is not a general purpose quantum computer and can't run Shor's algorithm.

        Besides, NSA is already able to break 1024 bit RSA using conventional computing (not to mention the possibility of much cheaper side channel attacks). See e.g. Schneier [schneier.com].

        If we are optimistic, it may be possible to factor a 1024-bit RSA modulus [before 2020] by means of an academic effort on [a] limited scale.

      Found the system specs for the test PCs, I wouldn't call them High End PCs except in the sense that the price was high end. The Xeon X5550 system appears to even be underclocked 1GHz below it's normal speed of 2.66/3.06GHz.

      Still, it'd take a big cluster of them to equal the performance of the V6. That's worth it right there.

  • Anyone interested in the D-wave story should be reading this article where Scott Aaronson explains the meaning of D-Wave's current results [scottaaronson.com].

    The takeaway points are:

    1. D-Wave's machine does demonstrate entanglement and quantum annealing
    2. There is no speed advantage whatsoever for quantum annealing over classical simulated annealing
    3. A correctly optimized version of classical annealing is actually faster than D-wave's solution
    4. D-Wave will only be able to make this machine work as a quantum computer (with the attendant speed gains) by implementing error-correction and other improvements that D-Wave have been loudly deriding for their entire history

    • According to this article [arstechnica.com], it actually is much faster than conventional computers... but only for problems that can be mapped to it well, and currently a lot of problems don't fall into that category.
