Abstract

A method for triggering a laser synchro-signal diode in a single-pass quantum cryptographic system is proposed. The method allows reducing the level of stray influence in an optical fiber from scattered laser radiation by \({\sim}\)2 orders of magnitude and increasing the length of a single-fiber communication line when generating a secret key to 95 km.

降低单程量子密码系统中光纤的杂散暴露水平

摘要

提出了一种在单通量子密码系统中触发激光同步信号二极管的方法。该方法允许减少的杂散影响的电平中的光纤从散射激光辐射通过\（{\ SIM} \） 2个数量级，并产生一个秘密密钥95公里当增加单光纤通信线路的长度。
