The number of bits in an encryption key and the number of qubits in a quantum computer trying to break it are not related in general and even if they are related, the relation is not necessarily a linear relation. Also quantum computers do not in general offer an advantage when it comes to breaking encryption keys. They do, for example, for RSA because it relies on integer factorization and there is a faster quantum algorithm than a classical one, they do not - as far as we know - for AES for example.
