论文摘要
在本文中，我们提出了一种使用分布变换为连续变量QKD设计的信息对帐协议。通过结合Copula和信息理论的工具，我们提出了一种用于为高斯调制的CVQKD协议提取独立的对称Bernoulli位的方法，我们称之为分布变换扩展（DTE）。我们得出了同源性和杂项测量值的最大对帐效率的表达式，在最后一个效率大于0.9时，在信噪比低于-3.6 dB的情况下，这是可以实现的。
In this paper, we present an information reconciliation protocol designed for Continuous-Variable QKD using the Distributional Transform. By combining tools from copula and information theory, we present a method for extracting independent symmetric Bernoulli bits for Gaussian-modulated CVQKD protocols, which we called the Distributional Transform Expansion (DTE). We derived the expressions for the maximum reconciliation efficiency for both homodyne and heterodyne measurements, which, for the last, is achievable with an efficiency greater than 0.9 at a signal-to-noise ratio lower than -3.6 dB.
