Quantum Secure Direct Communication Protocol Based on Four-Qubit Cluster State

Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 219)


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.
