Analysis of the Performance about Actual Quantum Key Distribution System Based on BB84 Protocol
Kai-guo Huang · 2012
Analyzed how did the fiber length, the attenuation and the average photon number of the pulse emitted by the single photon source affect the receive efficiency in the fiber channel quantum key distribution system based on the BB84 protocol.A theoretic model relative to the system was represented.It was shown by the emulation that the more average photon number was, the higher efficiency receiver would be, and the final key rate would be higher.
