- This paper demonstrates, for the first time, the feasibility of coexisting standard “classical” channels with a DV-QKD channel over multicore fibre, achieving a record-high coexistence of 11.2Tb/s. Previous works implemented emulated classical channels coexisting with DV-QKD. This paper uses real-time signals, representing carrier-grade classical/quantum channels. The earlier paper (“Coexistence of 9.6Tb/s classical and QKD channels over a 7-core MCF”, BICOP 2018) is listed in the Nature article “Quantum Information Processing with SDM Optical Fibres” (Communications Physics, 2020). This work is acknowledged in the article “On the QKD Integration in Converged Fibre/Wireless Topologies for Secured, Low-Latency 5G/B5G Fronthaul” (Applied Science, 2020).
