Quantum computing can break asymmetric cryptography in general (keypairs, i.e. wallets). There needs to be a migration to a safe mechanism at some point, but that's all fairly new. Right now, there are no QC risks yet. For future, the mitigation -as I understand it- is to use a wallet address only once, and e.g. bitcoin uses a technique to only expose the public key at the last possible moment such that time is on your side even in light of QC adversary. (I.e. no risk in "cracking" a keypair if the value was moved out already.)
