摘要

测量了光脉冲在不同传输距离和不同外界环境影响下基于差分相位编码和双不等臂M-Z相位编码系统的时间抖动,并根据时间抖动的分布情况建立了相位编码量子密钥分发系统中误码率和时间抖动关系的物理模型,给出了单光子脉冲一般波形函数和误码率之间的关系式,根据这个关系式可以得出确定波形单光子脉冲在确定时间抖动分布情况下系统误码率的结果.

Optical pulse will reach the receiver not at exact time instance due to the transmission through the long trunk fiber, and this phenomenon will effect on the bits error rate in the Quantum key distribution (QKD) system to some extend. The time jitter based on the differential phase shift quantum key distribution system and two asymmetric Mach-Zehnder interferometers is measured outdoors in different transmission distance and the physical model of the relationship between the time jitter and the quantum bit error rate is proposed. According to this relationship, the quantum bit error rate can be estimated for some optical pulse shape and some statistical distribution function.
