Performance Analysis of Wavelength Assignment Optimization Scheme for Hybrid Quantum-Classical Networks

Abstract

Abstract: In the hybrid quantum-classical networks, how the quantum signal wavelength and classical signal wavelength are distributed determines the degree that the quantum key distribution performance is affected by the classical optical signal noise. Aiming at the wavelength assignment optimization scheme based on the principle that the noise is minimal, the optimization degree of quantum key distribution performance is studied. The effects of wavelength interval and channel number on the performance of quantum key distribution are analyzed. Simulation results show that the optimization scheme improves the key generation rate and the furthest secure transmission distance of the networks. With a certain number of quantum and classical channels, the quantum key generation rate and the furthest secure transmission distance of the networks decrease with the increase of the wavelength interval. With a certain number of classical channels and wavelength intervals, the total key generation rate of the networks increases with the increase of quantum channel number, while the average key generation rate and the furthest secure transmission distance of each quantum channel both decrease.
