Dumb ass question but are these types of quantum computational algorithms applicable to Bitcoin-style computational mining in theory?
Quantum annealing isn't, as far as I can tell, so DWave (or D-Wave or whatever they call themselves) are out. And I don't see any obvious application of any of the algorithms I know of that are in BQP to cryptocurrency mining.
In any case, as other people suggested, the economics don't work. The DWave machine is expensive enough; as far as we know, no one's built a real QC of any size, for any price.
