In order to study the influence of different mixing methods of black carbon and non-absorbent aerosol on quantum channel parameters, according to the extinction coefficient of black carbon and sulfate and organic carbon aerosols under the mixed models of Core-shell and Maxwell-Garnett, the channel attenuation model is established and simulated, and the data relationship between black carbon volume fraction/channel correlation factor in mixed aerosol particles and double Pauli channel/associated bit flip channel parameters is studied. The influence of black carbon volume fraction and quantum signal transmission distance on the key security transmission rate is analyzed and the data simulation is carried out. The simulation results show that in the two mixed states, the attenuation of light quantum energy increases gradually with the increase of black carbon volume fraction, while the quantum security key generation rate decreases with the increase of black carbon volume fraction. Under different contents and models, the increase of channel correlation factor has a positive impact on the fidelity of channel teleportation, while the increase of the volume fraction of black carbon will weaken the fidelity of channel teleportation.
