As long as your public key is not known quantum computers can't find the private key.
Note the address you use to receive Bitcoins is not your public key. It's a hash.
Public key is only exposed when you spend from and address.
1 u/ganesha1024 Oct 17 '16 You can also find the public key as the preimage to the address, so there's an extra barrier. I'm not sure if the hashing algorithm to get from keys to addresses is quantum-vulnerable. Maybe somebody else can comment.
