摘      要：Compared with the fiber channel,the atmospheric channel offers the possibility of a broader geographical coverage and more flexible transmission for continuous-variable quantum key distribution(CVQKD).However,the fluctuation of atmospheric conditions will lead to the loss of performance in atmospheric quantum *** this paper,we study how temperature affects atmospheric *** mainly consider the temperature effects on the transmittance and interruption *** the numerical simulation analysis,it can be shown that the performance of atmospheric CVQKD is improved as temperature increases,with the other factors ***,the results in this work can be used to evaluate the feasibility of the experimental implementation of the atmospheric CVQKD protocols.
