Abstract:

We analyze the security of B92 quantum key distribution protocol in the non-ideal circumstances. A new quantum circuit model of B92 quantum key distribution protocol is raised to design simulation models under different noise channel models using the QCircuit. We introduce two indicators of BER and Rsec, and then the circuit models are designed to simulate and analyze the effectiveness and security of B92 key distribution protocol under different noise channel models. The experimental results show the new circuit design achieves the purpose of B92 key distribution protocol and the design approach is more universal significant. Therefore, it can be used to construct more quantum simulation models of different quantum key distribution protocols.

Key words: quantum key distribution; quantum circuit; B92; noise analysis; noise channels
