论文摘要
我们研究了具有连贯状态的离散相位调制的发送或不介绍协议。我们首先通过离散阶段调制来制定SNS协议的安全性。然后，我们提出分析公式以进行关键率计算。我们通过对原始SNS协议和SNS协议的离散阶段调制进行数值模拟，并使用Active-ODD-Parity配对（AOPP）进行两种经典通信。我们的数值仿真结果表明，只有$ 6 $的相值，SNS协议的关键速率才能超过线性界限，并且对于$ 12 $的相值，关键速率非常接近SNS协议的结果，并连续调制了相位。
We study the sending-or-not-sending (SNS) protocol with discrete phase modulation of coherent states. We first make the security of the SNS protocol with discrete phase modulation. We then present analytic formulas for key rate calculation. We take numerical simulations for the key rate through discrete phase modulation of both the original SNS protocol and the SNS protocol with two way classical communications of active-odd-parity pairing (AOPP). Our numerical simulation results show that only with $6$ phase values, the key rates of the SNS protocol can exceed the linear bound, and with $12$ phase values, the key rates are very close to the results of the SNS protocol with continuously modulated phase-randomization.
