利用差分相移和光子偏振，提出了两种量子密钥分配方案，即双编码BB84协议和双编码BBM92协议。这些协议的信息容量是原协议的两倍，并通过使用检测时隙、随机选择基和量子纠缠来保证协议的安全性。这些双重编码协议在现有技术下是可行的。
Using differential phase shift and photon polarization, we propose two quantum key distribution schemes, i.e. a double-coding BB84 protocol and a double-coding BBM92 protocol. The information capacity of these protocols is twice of the original protocols and their security is ensured by the use of detection time slots, random choice of bases and quantum entanglement. These double-coding protocols are feasible with present technology.
