Abstract: | Based on the techniques of the quantum remote state preparation viaa deterministic way, this paper proposes a quantum communicationscheme to distribute the secret messages in two phases, i.e., thecarrier state checking phase and the message state transmittingphase. In the first phase, the secret messages are encoded by thesender using a stabilizer quantum code and then transmitted to thereceiver by implementing three CNOT gates. In the second phase, thecommunicators check the perfectness of the entanglement of thetransmitted states. The messages can be distributed to the receivereven if some of the transmitted qubits are destroyed. |
