SKR and QBER calculations for a BB84-QKD link multiplexed with intense classical signal in a WSS-based node

This set will comprise a set of theoretical calculations on the effect of the filtering parameters of the WSS-based node on the quantum layer performance. In more detail, this data set will consist of the calculated QBER and SKR for the phase coding BB84 protocol by considering bandwidth and shape parameters of channel bands for Liquid Crystal on Silicon (LCoS)-based WSS nodes. Critical system requirements such as insertion loss and center frequency drifts are also considered. The obtained ultra-high sensitivity of QKD link performance on the filtering parameters of the WSS-based node, as confirmed by the generated data, can be useful for monitoring and control purposes at classical networks exploiting cascaded ROADMs.本数据集包含针对基于波长选择开关（Wavelength Selective Switch, WSS）的节点的滤波参数对量子层性能影响的理论计算。具体而言，本数据集将包含针对硅基液晶（Liquid Crystal on Silicon, LCoS）型WSS节点，通过考量信道带宽与波形参数后，针对相位编码BB84协议计算得到的量子误码率（Quantum Bit Error Rate, QBER）与密钥生成率（Secret Key Rate, SKR）。同时还纳入了插入损耗、中心频率漂移等关键系统参数的考量。经生成数据验证，量子密钥分发（Quantum Key Distribution, QKD）链路性能对WSS节点滤波参数具有极高的灵敏度，该结果可用于部署级联可重构光分插复用器（Reconfigurable Optical Add-Drop Multiplexer, ROADM）的经典网络的监控与调控工作。
