D-Wave will turn out to be whatever it is, but it's hard to find another company that's closer to commercializing quantum computing.

Given that, at best, it is only sort of a quantum computer, and definitely not what is normally meant with the phrase, and at worst in no way a quantum computer, I would say that there is a good chance that Bobs Banana Import is as close to commercializing quantum computing as this company is. It might still be true that nobody is closer than them, in the same sense as it is true that no company has a bigger presence on Jupiter than them.

Doesn't mean it is not money well spent by Lockheed et al., it just

"Conjectured" is too weak a statement here. It has been shown that a single-core normal classical CPU running a modestly optimized program is 12000 times faster than the D-wave computer at its speciality, the "D-wave problem":

With quantum computers you can tell if they exist or if they work but not both. The moment you determine both it becomes a regular computer. Or a brick.

This is a marketing scam. DWave doesn't have a quantum computer, at best they have a weakly quantum annealer. They could never even show that they have a single working qubit in their machine.

This article is not worthy of Nature, frankly it is deeply unethical for a peer-reviewed journal to publish such misleading crap. As an expert in the field I would expect to find this kind of bullshit in a tabloid or in a slashvertisement at best.

The Nature Publishing Group will feel the heat on this one, I hope they a

Indeed. Competent fraudsters, obviously, but that is all they have. If they had a real quantum computer, at the very least some spectacular benchmarks would have been forthcoming. Oh, wait, these are easy to verify and would give buyers and competitors legal claims if proven wrong.

It is amazing how easy to manipulate people that should know better are in this day and age. Historically, you would claim "magic". Now you claim "quantum computer", and suddenly many people lose all rationality. Pathetic.

Nature News isn't peer reviewed. Unless you consider the editor reading the journalist's article peer review because they're both journalists.

Hahahaha! Yes. What you say is true, well the latter half anyway. Nature *loves* the contraversial articles, so anything designed to stir up strong feelings and strongly worded letters and articles is just up their street. In other words, they are actually professional trolls (and not in the more modern usage of trolls meaning simply being a dick until you're banned).

No, it's not debunked; that is, no one has shown it not to be what's claimed. However it has been shown that even if it is what it claims it's no better than an optimized classical simulated version. It's like someone claims they have a quantum chicken, and it may be quantum chicken, but it still can't cross the road faster than a fast non-quantum chicken.

That is not what I meant was debunked. What I meant (being a Computer Scientist and not a Physicist) was the implicit claim that this performs massively better at some computations than classical computers for the same money. In the literal sense, you are right, of course, D-Wave is very careful what they claim, the fraudulent claims only turn up in peoples expectations.

If they cannot execute Shor's Algorithm for factorization it isn't a quantum computer, and I haven't seen anything that can solve Shor's algorithm in a single operation so it isn't a quantum computer. It really is that simple.
