论文摘要
本文介绍了从高空平台（HAP）部署量子密钥分布（QKD）的可行性研究，以确保未来的通信应用程序和服务。该论文对最先进的HAP技术的状态进行了详尽的审查，并总结了HAP可以为QKD服务带来的好处。本文中介绍了详细的链路预算分析，以评估从平流层HAPS在20公里高度飞行的QKD的可行性。结果表明，在大多数操作条件下，宽阔的链路预算带来了使用发散光束的可能性，从而简化了在HAP和地面上光学系统的指向，获取和跟踪（PAT），从而有可能扩大QKD可能是可行解决方案的未来用例。
This paper presents the feasibility study of deploying Quantum Key Distribution (QKD) from High Altitude Platforms (HAPs), as a way of securing future communications applications and services. The paper provides a thorough review of the state of the art HAP technologies and summarises the benefits that HAPs can bring to the QKD services. A detailed link budget analysis is presented in the paper to evaluate the feasibility of delivering QKD from stratospheric HAPs flying at 20 km altitude. The results show a generous link budget under most operating conditions which brings the possibility of using diverged beams, thereby simplifying the Pointing, Acquisition and Tracking (PAT) of the optical system on the HAPs and ground, potentially widening the range of future use cases where QKD could be a viable solution.
