基于连续变量量子密钥分发系统，提出了一种自发同步的方案。这种方案能有效地克服连续变量量子在光通信过程中受到环境因素的影响，实现连续变量量子密钥分发端和接收端系统之间的同步。从理论上介绍了这种同步方案的机制，并在连续变量量子密钥分发系统上对这种同步方案的可行性进行了验证。在实验所得数据的基础上分析了这种同步方案所需时间和成功率等关键性能指标。

A method of spontaneous synchronization based on a continuous variable quantum key distribution (CV-QKD) system is proposed. This method can effectively overcome the disturbance effects which are generated by the environment in the transmission process of continuous variable quantum. The scheme realizes the synchronization between the sending terminal and the receiving tevminal. The mechanism of this synchronization scheme is introduced theoretically, and then the feasibility of this synchronization scheme is verified based on a continuous variable quantum key distribution system. Based on the experimental data, the key performance indicators for this synchronization scheme such as required time and successful probability are analyzed.
