连续变量测量设备无关的量子直接通信
摘要
Abstract
The security of classic communications relies on encryption technology,and the privacy of the key determines the security of communications,but this security is threatened by the explosive growth of computing power.In the field of quantum cryptography,quantum secure direct communication provides a new communication mode that can modulate secret information on quantum states and directly transmit it in quantum channels.Its security is guaranteed by quantum physical mechanisms.The quantumsecure direct communication scheme built using continuous-variable quantum states is highly compatible with existing telecommunications networks and can provide higher communication rates within safe distances.Aiming at the problem that the imperfection of measurement devices is vulnerable to eavesdroppers in practical applications,this paper proposes a continuous variable measurement-device-independent quantum secure direct communication protocol based on entanglement switching,and analyzes its security.At the same time,based on the symmetry of the protocol,a quantum dialogue protocol suitable for two-way communication is designed.关键词
