We attempt to develop Shannon's concept of the unicity distance into the quantum context. Based on the definition of information-theoretic security for quantum cryptography, we present a quantum probabilistic encryption algorithm with bounded information-theoretic security, and then work out its quantum unicity distances. The result shows that quantum unicity distance is much bigger than the unicity distance of classical cryptography.
