摘要/Abstract

摘要： 在量子-经典混合光网络中，量子信号和经典信号波长如何分配决定了量子密钥分发性能受经典光信号噪声影响的程度。针对基于量子信号所受噪声最小化原则的波长分配优化方案，研究了量子密钥分发性能的优化程度；分析了波长间隔、信道数目等因素对量子密钥分发性能的影响。仿真结果表明，优化方案提升了网络的密钥生成率以及最远安全传输距离；在量子信道和经典信道数目均一定的情况下，网络的量子密钥生成率和最远安全传输距离随着波长间隔的增大而减小；在经典信道数目和波长间隔一定的情况下，随着量子信道的增多，网络的总密钥生成率增大，而每个量子信道的平均密钥生成率和最远安全传输距离均减小。

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.
