论文摘要
该研究考虑了具有多个外部信号的线性系统中相位随机共振的新效果，这些信号会影响量子通信。在量子键分布（QKD）的量子纤维（QKD）中，量子纤维（QKD）的量子和多个经典信号的线性共同传播显示了相位随机共振。经典信号的SNR与相位噪声的依赖性取决于信号的波长在一定的相位噪声范围内具有最大值。结果确定了一组传输参数，这些传输参数将减少QKD系统中量子信号的干扰。
The study considers the new effect of phase stochastic resonance in a linear system with multiple external signals that can influence quantum communication. The phase stochastic resonance was shown in a linear co-propagation of the quantum and multiple classical signals in the multicore fiber of the quantum channel of Quantum Key Distribution (QKD). The dependence of SNR vs phase noise of classical signal could have a maximum at a certain range of phase noise depending on the wavelength of the signals. The results determine the set of transmission parameters that would produce less interference with the quantum signal in QKD systems.
