摘　　要：基于相位编码的量子密钥分配协议,对微弱光脉冲采用差分相位编码,采用双不等臂M-Z干涉仪系统进行解码。在经典计算机上用Delphi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 phase-shift quantum key distribution with Phase-shift, and the bit information is decoded at Bob＇ protocol, the quantum bit information is encoded s side by M-Z interferometer. The corresponding programme is written with Delphi software on classical computer, thus realizing the simulation of phase-shift quantum key distribution protocol. Experiment indicates that the simulation of phase-shift quantum key distribution protocol on classical computer is completely possible.
