That's the holy grail, quantum keys, that you can only use once,, you just have a token, and when you transfer it once you can't double spend it because the signing keys were lost while signing.
But this also means that you can't really backup your keys with redundancy, so if your hardware wallet loses its quantum state, you lose your money.
So we better work with what we have now and figure out how to prevent double spending at scale, even if we have to accept gradient of confidence, just like we have confirmations number and 1 confirmation is not as final as 6 or 100.
