Do you really think they're going to get this amazing world's first quantum computer and go, yep lets use it to destroy that Bitcoin thing? Even if it was powerful enough to do that. They'll use it for important stuff like spying on our own citizens, developing better ways to kill things, and supporting the military industrial complex answering scientific questions that have never been answered before about physics, space etc.
FYPFY but no I don't think Bitcoin will be a high priority
Confirming. Don't worry though, I doubt they have any universal quantum computer with more than 32 qubits right now (not necessarily a least upper bound).
