基于非信任光源的诱骗态量子密钥分发

摘要

The security of the weak + vacuum decoy state protocol with unttusted sources is studied, and the effects of internal statistic fluctuation on the final key rate and the transmittance distance are discussed.The results showed that both the maximum safe transmission distance and final key generation rates are reduced when the statistic fluctuation is considered.%通过考虑Alice设备内部的统计波动,研究了弱真空诱骗态量子密钥分配方案中该统计波动对双向系统非信任源的密钥产生率和最大安全距离的影响.研究表明:该波动会在一定程度上降低密钥产生率和最大安全传输距离.
