摘要
我们提出了一种地空量子密钥分发（QKD）任务概念以及 accompanying 用于开发近地轨道立方体卫星载荷的可行性研究。量子信息由单光子承载，二进制码由光子的偏振态表示。地面与卫星间纠缠光子的分发可用于认证链路量子特性：保证不会发生窃听。通过将纠缠光子源置于地面，空间段仅包含较简单的探测系统，使其能实现于紧凑外壳中，符合 12U 立方体卫星标准（12 dm³）。这降低了项目总体成本，使其成为未来欧洲量子通信卫星任务探路者的理想选择。空间段也比包含光源的段更具通用性，因其兼容多种 QKD 协议（不限于纠缠光子方案）并可用于量子物理实验，如纠缠退相干研究。其他可能实验包括大气传输/湍流表征、暗区测绘、精细指向与跟踪以及精确时钟同步；这些对未来全球尺度量子通信工作均至关重要。
