The folks at D-Wave have published some interesting & perfectly legitimate papers on techniques for optimizing parallel tempering simulations (including on non-quantum computers, but especially helpful if you have a quantum computer handy for quantum PT, which is how they vaguely describe their actual setup). That suggests to me that at the very least they have some legit people who are good at solving stochastic optimization problems & are not fraudulent.
This is false. I guarantee you, scientists would be very interested if they actually demonstrated entanglement. For example, in the slides of the linked talk, the presenter goes over a very general measure of entanglement which allows you to construct after-the-fact a "witness" of entanglement. It is respected theory, and a credible last-resort approach; no numbers. His latest preprint[1] doesn't have a clear claim either. The Newscientist section refers to a conference 2 weeks ago, without published abstracts, procedings, or video. I'll believe it when I see it (there's no indication Aram's quote is in context, but maybe he has).
The first thing any qc lab does when they get their second qubit is make an entangled state and measure Bell Inequality violation. D-wave's lack of interest in this or in running Shor[2] is very telling. Everybody wants to run Shor, it's where the money is.
