Quantum Identity Authentication Protocol Based on Three-Photon Quantum Error Avoidance Code

Quantum identity authentication is one of important techniques in quantum secure communications. So far, most of the quantum identity authentication protocols proposed are based on noise-free environments. However, due to the existence of quantum noise in quantum channels is inevitable, the noise immunity is very important to quantum identity authentication. In this paper, a novel quantum identity authentication protocol based on three-photon error avoidance code is proposed. In this protocol, quantum information is encoded on the noiseless subsystem, so the protocol can effectively resist on the interference of noise in the quantum channel to information transmission. And the comprehensive analysis of antinoise performance and the security analysis on various eavesdropping attacks shows that the new protocol proposed in this paper has not only good anti-noise performance, but also good security.
