Nothing, because there are no fully functioning quantum computers yet.

cryptography in a quantum setting is not fully understood, however from a technical perspective, quantum randomness may strengthen cryptography more than hurt it. Also someone correct me if im wrong, but the cryptography behind most coins works specifically on a byte system, im not sure how well a quantum computer would even help you, unless its made from scratch to mine btc, and that wouldn't be for long enough to plan for.

You should just buy QRL instead of thinking about these. It's on Bittrex.
If you had a quantum computer, you could just extrapolate private keys from public ones in no time. Praise Allah there can be only one true quantum computer per universe, and the humans don't have it.
