多用户无源光网络量子密钥分发系统研究

摘要

The concept of passive optical network quantum key distribution (PON-QKD) is put forward, and two schemes of PON-QKD system with independent and shared fiber transmissions are compared. Also, a multi-user PON-QKD system which employs a modified plug-and-play system is proposed. And then the per-formance and feasibility of this PON-QKD system are analyzed and demonstrated.%提出了量子安全保证的无源光网络(PON)概念,对比分析了独立传输和共纤传输量子无源光网络的特点.设计了基于改进的即插即用系统的多用户无源光网络量子密钥分发(PON-QKD)系统,并对该系统的性能和可行性进行了论证.
