| 摘要 | In order to improve the reliability and security of quantum direct communication, this paper proposed a new quantum secure direct communication protocol based on the entanglement properties of cluster state and EPR entangled pairs. This protocol takes four-quit cluster state as the information carrier, using unitary transformation, through quantum information states to do the Bell-based measurements to interpret the secret messages. The cluster state is better than W state of entanglement properties, has a higher efficiency of the communication, and is more comfortable to use for information carrier. © 2013 Springer-Verlag. |
