You can't mine with a quantum computer.

You can only generate the privatekeys. That is what some groups will try: bringing back the lost coins or 'shalecoins' to the blockchain as active coins. https://bitcointalk.org/index.php?topic=5134441.0

Quantum computers are computers which exploit quantum mechanics to do certain computations far more quickly than traditional computers. https://en.bitcoin.it/wiki/Quantum_computing_and_Bitcoin
generating the privatekey: yes
hashing the next block: no

Deriving the private key of old addresses that got reused and still have balance: eventually.

Deriving the private key of old address with no outgoing transactions: no.

The majority of "lost" coins fall in the latter category. Quantum computing can't bring back old coins just like it can't bring back your grandmother.
