Abstrakt:	We calculate the magnitude of cross phase modulation (XPM) induced by classical channels, and analyze its impact on quantum secure key rate. The results show that the XPM induced by classical signals is small and its impact on the quantum key distribution can be neglected. [ABSTRACT FROM AUTHOR]
