摘　　要：基于差分相位编码的量子密钥分配协议,对弱相干光脉冲采用相位调制,采用非对称M-Z干涉仪系统进行差分解码。在经典计算机上用Matlab编制相应的程序,实现了相位调制的量子密钥分配协议仿真。研究表明,在经典计算机上仿真相位调制的量子密钥分配过程是完全可行的。Based on differential phase shift quantum key distribution protocol,the quantum bit information is modulated with phase shift,and the bit information is decoded at Bob＇s side by an asymmetric M-Z interferometer.The corresponding program is written with Matlab software on classical computer,thus realizing the simulation of phase-shift quantum key distribution protocol.Research indicates that the simulation of phase-shift quantum key distribution protocol on classical computer is completely possible.
