Quantum Mining isn't a thing yet. As far as I'm aware we're still a ways out from anyone even trying it. I can get a little time on a DWave in soCal but idk it it'd be enough to demonstrate anything significant.

As I understand it though 1 quantum computer with enough qbits could easily crack every lock we use on the net & out hash the entire bitcoin network, so.. Yeah, I'm just trying to connect to a billion other me's rigs & via quantum tunnling share solutions.

There are of course some more technical limitations here & realistically if such a device were created it would be implemented with a new type of coin.
