Not how it works as far as I know. If people start mining with a quantum computers the difficulty will increase making it even more secure (one of bitcoins main features). Traditional computers will drop out due to lack of rewards and more powerful quantum computers will enter and compete with the original quantum computers and the cycle continues. It’s a self balancing system.
QC would be completely devastating to bitcoin. Anyone with a sufficient QC could break any block of the bitcoin chain they want, essentially giving all the bitcoins to themselves. There are other cryptocurrencies that are quantum-resistant, but bitcoin itself would be done.
I would assume in the face of that the bitcoin network would have to change its consensus to include quantum resistance. I think this is possible but not sure
