摘      要：Atmospheric effects have significant influence on the performance of a free-space optical continuous variable quantum key distribution(CVQKD)*** this paper,we investigate how the transmittance,excess noise and interruption probability caused by atmospheric effects affect the secret-key rate(SKR)of the *** signal wavelengths,two weather conditions,two detection schemes,and two types of attacks are considered in our *** expression aims at calculating the interruption probability is proposed based on the Kolmogorov spectrum *** results show that a signal using long working wavelength can propagate much further than that of using short ***,as the wavelength increases,the influence of interruption probability on the SKR becomes more significant,especially within a certain transmission ***,interruption probability must be considered for CVQKD by using long-signal ***,different detection schemes used by the receiver will result in different transmission distances when subjected to individual attacks and collective attacks,respectively.
