本文提出了一种对每一个单光子信号进行相位和偏振两种 编码调制的联合调制量子密钥分配(QKD)系统. 结合复合QKD系统的双速协议, 本文给出了在理想情形下可以通过一个信号光子生成两比特密钥的QKD协议, 明显提高了QKD协议的内禀光子利用率. 在稳定性方面, 本文发展了联合调制的Michelson型QKD系统, 从而在原理上解决了联合调制QKD系统的稳定性问题.

We suggest a combined modulation quantum key distribution (QKD) system which encodes each single-photon signal with both phase modulation and polarization modulation. With the aid of dual-velocity protocol of hybrid QKD system, we construct a scheme to realize this combined modulation QKD which generates two-bit key with one signal for increasing the efficiency of QKD. We also develop a combined modulation Michelson QKD system, then solve the stability problem of the combined modulation QKD system in principle.-
