ROFL
can we use these quantum computers to mine
Have you even seen what current QC's look like? Massive, use liquid He cooling, mega $$$$$...
Not bloody likely for many a years to come

Oh... Bummer. But the APIs will be released soon, so maybe we can at the very least begin developing mining software for these things. And if someone with enough capital can rent one out (Seeing as IBM wants to make them commercially available) he/she can dominate with their superior computing power. Maybe not probable, but possible?
