Let me try to summarize the main point I’ve been trying to get across this whole time. (*) D-Wave founder Geordie Rose claims that D-Wave has now accomplished its goal of building a quantum computer that, in his words, is “better at something than any other option available.” This claim has been widely and uncritically repeated in the press, so that much of the nerd world now accepts it as fact.However, the claim is not supported by the evidence currently available.See here for more info; I’ll be traveling then and won’t be able to make it.I don’t know whether the performance comparisons to Matthias Troyer’s and Alex Selby’s code will be among the topics discussed, or if there will be an opportunity to ask questions about such things.Instead, Mc Geogh used the time to enlighten the assembled experts about what quantum annealing was, what an exact solver was, etc.etc., then repeated the speedup claims as if the more informative comparisons simply didn’t exist.Did it make business sense for Google to buy a D-Wave machine? Should have acted differently, in my interaction with Mc Geoch?And, I’m afraid to say, I jumped in to the discussion of all of those questions—because, let’s face it, there are very few subjects about which I don’t have an opinion, or at least a list of qualified observations to make. It would have been better to sidestep all the other questions—not one of which I know the answer to, and each of which admits multiple valid perspectives—and just focus relentlessly on the truth of assertion (*).

Incredibly, she spoke for more than an hour, without once mentioning the USC results that found that simulated annealing on a standard laptop (when competently implemented) handily outperformed the D-Wave machine, or making any attempt to reconcile those results with hers and Wang’s.Even if not, isn’t it possible that the startup will manage to develop an effective gene therapy sometime in the future? And anyway, at least they’re out there to make gene therapy work!So we should all support them, rather than relentlessly criticizing.I left without asking questions, not wanting to be the one to instigate an unpleasant confrontation, and—I’ll admit—questioning my own sanity as a result of no one else asking about the gigantic elephant in the room. Among the many interesting comments below, see especially this one by Alex Selby, who says he’s written his own specialist solver for one class of the Mc Geoch and Wang benchmarks that significantly outperforms the software (and D-Wave machine) tested by Mc Geoch and Wang on those benchmarks—and who provides the Python code so you can try it yourself.Also, Igor Vernik asked me to announce that on July 8th, D-Wave will be giving a technical presentation at the International Superconducting Electronics Conference in Cambridge.
