That's not entirely fair. D wave is attempting to use quantum effects anneal to solutions faster than a classical computer would. It's not what we would usually think of as a quantum computer, but its in the right ball park. No?

Well my desktop also uses quantum effects. So did valve computers at the time, thus, I don't think anybody ever built a "classical computer".

Yes, that's the definition they use on their site. No, I don't think applying it verbatim to my computer is unfair.

Ok, they created a different kind of classical computer. One that may be able to solve some kinds of problems better, like a specialized computer often does. Yes, it could have been huge (but wasn't - too bad). But it's not a quantum computer, and their marketing is dishonest.

They claim to make use of quantum effects -- in an abstract sense, quantum tunnelling across potential peaks in the solution space to access classically unreachable absolute minima. If that claim is true, then I agree that D-Wave is a type of quantum computer. What is disputed, I believe, is the truth of the claim.
