Of course key management would be a bit difficult, although it would

A 'pure' layman's question (I understand nothing of quantum): There is
quantum computer on the one side and quantum encryption (for secure
transfer of keys) on the other side, isn't it? How about using quantum
encryption to transfer the messages themselves? Could that be broken
even with quantum computers?

Thanks.
