Synergistic Resource Allocation with Key Generation and Consumption Matching in Quantum Secured Multicore Fiber Optical Networks

In this paper, an innovative algorithm named quantum key distribution transceiver planning for key generation and consumption matching (QTP-GCM) is proposed to solve the problem of mismatch between key generation and consumption. Furthermore, the classical and quantum signal layered interleaved (CQLI) algorithm is proposed to achieve synergistic transmission of classical and quantum signals in multicore fiber networks. The simulation results show that CQLI scheme can improve the optical signal-noise ratio (OSNR) up to 5.32dB and improve the synergistic degree up to 0.536 compared to conventional channel allocation algorithm.
