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.
