There are no quantum encryption algorithms.  None.

What we have is quantum key exchange, where you use a handful of qubits
to negotiate a random session key in a way that an eavesdropped cannot
listen in on the transaction.  If you're willing to burn up a _lot_ of
qubits, you can turn this into the one-time pad.  But either way, all
you're doing is transferring key material in a way that can't be
eavesdropped upon -- nothing more.
