论文摘要
我们使用二进制相干状态和选择后分析了基于同性恋的连续变量量子键分布协议的集体攻击的安全性。在渐近场景中，我们得出了秘密密钥速率的下限，并将其用于对称高斯通道的情况下进行数值优化。
We analyze the security against collective attacks for a homodyne-based continuous-variable quantum key distribution protocol using binary coherent states and postselection. We derive a lower bound of the secret key rate in an asymptotic scenario, and numerically optimize it for the case of a symmetric Gaussian channel.
