If Quantum Computing is released into the wild and starts to attack bitcoin , what measures would we see to mitigate these attacks?

Hope some miners can also get a quantum computer to compete with mining and switch to an algorithm for the keys that would take the QC longer than it's expected Quantum decoherence time by a factor of billions upon billions.

What if the government controls the Quantum computer , and there isn't anyone to fight back? Would that spell the end of Bitcoin? And if there is , would it be necessary to move to QC resistant cryptography?

Back to the drawing board. If any entity gets control of 51% of the mining and there is no way to wrest back control, then Bitcoin is insecure and virtually worthless.

if this did happen and bitcoin did bring down the banks , so there is no "currency" system , i wonder what would come next.
