This article seems to say the ADAIABATIC quantum computers aren't better than classical ones. In other words other quantum computers might still be useful where D-WAVE's adiabatic approach will not?
The adiabatic quantum computer from D-WAVE has been criticized previously for not being a 'real' quantum computer.
- mturmon 16y agoFrom the article: "Furthermore, all types of quantum computers have been shown to be mathematically identical, so if one won't work, none of them will." This is vague, and does not say if it pertains to only QC's used on problems in NP, or in general. As other posters have noted, the subject resists simplification.

- hugh3 16y agoQuantum computers work just fine, they just can't solve NP-complete problems faster than a classical computer. This is fine, since nobody except D-wave and their somewhat credulous investors (including folks who should have known better) ever really thought they would.
