Last I heard about D-Wave, official word was something along the lines of "There's something interesting going on in this machine (even though it's not quite what our models lead us to expect from a quantum computer), and it's better than regular hardware at some classes of problems, but we're not sure what's going on, or exactly why it's better.". Has there been new news in the past year or so?
