Can't find any explanation of what the supposed D-Wave quantum computer actually does. Null hypothesis: pure hype.
@Meaningness SciAm appears to agree with me, which is never a good sign: http://blogs.scientificamerican.com/guest-blog/2013/05/17/is-it-quantum-computing-or-not/ …

@St_Rev Yeah, the current claim is that it does quantum annealing. Not clear how/whether that beats regular annealing. Reading McGeoch now. -
@Meaningness 3 possibilities: D-Wave snuck in a mechanical Turk, D-Wave got really lucky, D-Wave actually works. Guess we'll know soon enuf. -
@St_Rev Or it does something that is uninteresting once you strip out the hype. McGeoch paper is first semi-explanation. Fairly dense... -
@Meaningness Snap-solving NP-hard problems is pretty interesting if you're an airline, no? -
@St_Rev They don’t even claim to solve NP-hard problems. -
@Meaningness What's the difference between NP-hard and NP-hard optimization? -
@St_Rev Quantum annealing, like conventional annealing, doesn’t guarantee a global optimum solution. -
@Meaningness Good enough for a couple trillion dollars' worth of applications, though. - 1 more reply
