You can construct entirely secure ciphers with quantum mechanics
(although not a quantum *computer* per se: "quantum cryptography" is not
just "ordinary cryptography done on a quantum computer"). That's not
secure as in "it would take an unfeasibly long time to break", that's
"cannot be broken, unless quantum mechanics is wrong".
