摘要

Hwang(2003)提出了一种量子密钥分发(QKD)的诱饵状态方法。在Hwang的提议中，诱饵态的平均光子数约为2。本文提出了一种新的以真空或弱相干态作为诱饵态的诱饵态方案，并讨论了其优点。

Quantum key distribution with vacua or dim pulses as decoy states

Hwang (2003) has proposed a decoy state method in quantum key distribution (QKD). In Hwang's proposal, the average photon number of the decoy state is about two. This paper propose a new decoy state scheme using vacua or very weak coherent states as decoy states and discuss its advantages.
