LLO-CV-QKD Key Dataset

Dataset with the raw keys before post-processing, using a CV-QKD system with true local oscillator. The sender's keys consist of values that follow a normal distribution, according to the Gaussian modulation scheme. The receiver's keys have been obtained by applying a software-defined pilot-tone assisted demodulation algorithm. Since this is CV-QKD, the keys are expressed as float numbers, and are separated into the actual key (x_key, y_key) and the fraction of the key used for parameter estimation (x_pe, y_pe).本数据集包含后处理前的原始密钥，采用搭载真实本地振荡器（Local Oscillator）的连续变量量子密钥分发（Continuous Variable Quantum Key Distribution, CV-QKD）系统。发送端密钥按照高斯调制方案生成，其数值服从正态分布；接收端密钥通过软件定义的导频音辅助解调算法得到。由于本系统属于连续变量量子密钥分发场景，密钥以浮点数形式表示，并被划分为实际密钥（x_key、y_key）与用于参数估计的密钥片段（x_pe、y_pe）两部分。
