Quantum effects or quantum computation? Technically our whole universe is a quantum effect, but most of it can’t be regarded as doing information processing, and of the parts that do information processing, we don’t yet know of any that are faster on account of quantum superpositions maintained against decoherence.
I’m not sure where the line would be drawn; I think it’s possible that neurons are getting speedups by exploiting quantum effects. I don’t think it’s using it to solve problems that aren’t in P.
My understanding is that any speedup would be fairly implausible, I mean isn’t the whole lesson of l’affaire D-Wave that you need maintained quantum coherence and that requires quantum error-correction which is why Scott Aaronson didn’t believe the D-Wave claims? Or is that just an unusually crisp human-programming way of doing things?
