首发时间:2017-12-06
摘要:为了降低在量子信号与经典光信号共存的网络中,四波混频、拉曼散射和器件隔离度不足引起的串扰对量子信号的影响,本文设计了一种非等间隔的灵活频谱分配方案,使得量子通信与经典光通信能在栅格灵活光网络中融合传输与交换。并针对提出的频谱分配方案,给出了一种整数线性规划计算方法,进行了一系列的理论分析与仿真验证,充分说明了该方案的可行性。本文提出的非等间隔的频谱分配方案为未来搭建灵活的融合型量子通信网络奠定了基础。

A Flexible Spectrum Allocation Scheme of Integrated Quantum Communication and Classical Optical Communication
Abstract:In order to reduce the influence of four-wave mixing, raman scattering and crosstalk caused by low device isolation on the quantum signal in the coexistence network of quantum signals and classical signals, an unequal frequency spacing allocation scheme is designed to make quantum communication and classical optical communication coexist harmoniously in the spectrum-flexible optical networks. Aiming at the proposed spectrum allocation scheme, an integer linear programming method is given and a series of theoretical analyzes and simulations are carried out to verify its feasibility. The proposed unequal frequency spacing allocation scheme lay the foundation for the future to build a flexible converged quantum communication network.
