摘要：

We investigate how a classical private key can be used by two players, connected by an insecure one-way quantum channel, to perform private communication of quantum information. In particular we show that in order to transmit n qubits privately, 2n bits of shared private key are necessary and sufficient This result may be viewed as the quantum analogue of the classical one-time pad encryption scheme.
