| 摘 要： | 讨论了利用法拉第镜补偿光在光纤中传输的偏振波动,介绍了量子密码术中基于法拉第镜的即插即用系统,并对即插即用系统进行简单相位编码分析。在系统中干涉脉冲遵循确切相同的路径,确保非常高的稳定性和自我补偿,使用法拉第镜自动补偿光纤中的任何双折射效应和偏振相关损耗。

| Abstract: | To compensate for all polarization fluctuations in the transmitting fiber by using Faraday mirror is discussed, and "plug- and- play" system based on Faraday mirror for quantum cryptography is introduced, phase-encoding analysis in brief for plug- and- play system is implemented. The interfering pulses follow exactly the same spatial path, ensuring very high stability and self-compensating. The use of Faraday mirrors compensates for automatically any birefringence effects and polarization dependent losses in the transmitting fiber. |
