A Protocol for Bidirectional Quantum Secure Communication Based on Genuine Four-Particle Entangled States
By swapping the entanglement of genuine four-particle entangled states, we propose a bidirectional quantum secure communication protocol. The biggest merit of this protocol is that the information leakage does not exist. In addition, the ideas of the "two-step" transmission and the block transmissio...
