We analyse the finite-size security of the efficient Bennett-Brassard 1984 protocol implemented with decoy states and apply the results to a gigahertz-clocked quantum key distribution system. Despite the enhanced security level, the obtained secure key rates are the highest reported so far at all fibre distances.
我们分析了采用诱骗态实现的高效1984年贝内特-布拉萨德协议的有限尺寸安全性，并将结果应用于千兆赫兹时钟的量子密钥分发系统。尽管安全级别有所提高，但在所有光纤距离下，所获得的安全密钥率是迄今为止报道的最高值。
