Popis:	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. Comment: 5 pages, 3 figures
