同步技术是连续变量量子密钥分发系统的核心技术之一,能实现通信双方的实时通信,确保量子信息的有效提取。本文提出了一种新型的同步方案,能有效克服量子信道噪声及误码的影响,实现发送端和接收端的准确同步。文章从理论上介绍了方案的同步机制,并对其性能进行了仿真分析。

Synchronization is one of the key techniques in continuous-variable quantum key distribution system,which can realize real-time communication so that secret information can be extracted effectively. A new synchronization scheme was presented in this paper that can overcome the code error arising from excess noise introduced by quantum channel and reach accurate synchronization between sender and receiver. In the paper,synchronous mechanism was introduced theoretically,and the corresponding performance was analyzed in simulation.
