【Abstract】 By analyzing and calculating the key generation rate for the free space quantum key distribution system,the relationship between the key generation rate and the drop concentration of the cloud or fog for quantum key distribution through cloud or fog was released.It gave out the maximum drop concentration of the cloud or fog and the corresponding shortest meteorological range for effective free space quantum key distribution.更多还原
