I should clarify - I agree with you in that #2 is demonstrably false. But Aaronson has gone back and forth on his skepticism for D-Wave.[1] He is now rightfully back in the skeptical camp, however. My main point was that acknowledged experts have gone back and forth on this and there have been conflicting publications about D-Wave's computers. Now that I review the research again, it looks like it's been experimentally shown to have legitimate entanglement implemented in the computers, but the consensus is indeed that there is no quantum speed up or improvement or classical computers. Thanks for the reply though, I've edited the original comment. [1]: http://www.scottaaronson.com/blog/?p=639 http://www.scottaaronson.com/blog/?p=639
