Abstract: | Based on the techniques of the quantum remote state preparation via
a deterministic way, this paper proposes a quantum communication
scheme to distribute the secret messages in two phases, i.e., the
carrier state checking phase and the message state transmitting
phase. In the first phase, the secret messages are encoded by the
sender using a stabilizer quantum code and then transmitted to the
receiver by implementing three CNOT gates. In the second phase, the
communicators check the perfectness of the entanglement of the
transmitted states. The messages can be distributed to the receiver
even if some of the transmitted qubits are destroyed. |
