Quantum Secure Direct Communication with Cluster State
Guoyou Wang, Fang Xi-Ming, Tan Xiao-Hui · Chinese Physics Letters · 2006
We propose a novel protocol for quantum secure direct communication with cluster states. In this protocol, the two legitimate users, Alice and Bob, can directly transmit the secret messages by using the Bell-basis measurement and Z -basis measurement, respectively, in classical communication. Since our quantum secure direct communication protocol is based on the cluster state, it is easily processed by a one-way quantum computer.
