“The way I thought about it was that we’d have succeeded if: (a) someone bought one for more than $10M; (b) it was clearly using quantum mechanics to do its thing; and (c) it was better at something than any other option available. Now all of these have been accomplished, and the original objectives that we’d set for ourselves have all been met.” (Geordie Rose, 2013, source)
While D-Wave investor Steve Jurvetson predicts that D-Wave’s computers will soon run “faster than the universe”, in a different planet, Scott Aaronson and Greg Kuperberg claim D-wave’s computers show no speedups and are “worth $0”. Luckily for D-Wave, the public will never read 300++ blog comments. I confess I have no life, so I’ve read most of them.
We’ll soon find out who’s right, probably in less than a year’s time.
Personally, my opinion on the matter is very bland and boring. I believe that in the future, gate model QCs will outshine D-wave’s QCs (because they allow better error correction), but for now we can learn some interesting physics and engineering from D-wave’s QCs.
