Lightweight Unmanned Aerial Vehicles (UAVs) have seen a huge increase in commercial uptake in recent years, but their applications have been limited, in part by the inability to securely communicate highly sensitive data back to the ground. Project Q-DOS (QKD for Drones with Optimal Size weight and power) will solve this problem by delivering a unique quantum encrypted communication system with an eavesdropping detection feature between an airborne platform and a ground-based station. This hyper-secure system is based on Quantum Key Distribution (QKD), which provides future proof communications security combined with the novel ability to detect eavesdroppers. A key challenge is meeting the demanding Size, Weight and Power (SWaP) requirements as the system will have to be deployed on a lightweight (under 7kg) drone. This will be achieved by using the novel integrated quantum optical QKD chips combined with flight-proven optical communications system developed by project members. We expect the outcome of this project not only to be a step change in capability in the secured drone market (both military and commercial), but to open up a significant number of areas, moving QKD away from niche applications and towards mainstream adoption.The Centre for Quantum Photonics at the University of Bristol is one of the world leaders in the development of integrated quantum photonics technology. It has a wealth of practical knowledge (also in free-space QKD experiments) which it hopes to contribute to the project. In particular, UoB will collaborate in the development of detector technologies and provide detector characterisation facilities, provide a combination fast and slow driving electronics, all combined with significant person-power of expertise of QKD systems and field experiments.

近年来，轻型无人机（UAV）的商业应用大幅增加，但其应用受到限制，部分原因是无法将高度敏感的数据安全地传回地面。Q-DOS项目（具有最佳尺寸重量和功率的无人机QKD）将通过在机载平台和地面站之间提供具有窃听检测功能的独特量子加密通信系统来解决这个问题。这种超安全系统基于量子密钥分发（QKD），它提供了未来证明通信安全性与检测窃听者的新能力相结合。一个关键的挑战是满足苛刻的尺寸，重量和功率（SWaP）要求，因为该系统必须部署在轻型（7公斤以下）无人机上。这将通过使用新型集成量子光学QKD芯片与项目成员开发的飞行验证的光通信系统相结合来实现。我们希望该项目的成果不仅是安全无人机市场（包括军用和商用）能力的一步变化，而且还将开辟大量领域，使QKD从利基应用转向主流应用。布里斯托大学量子光子学中心是集成量子光子学技术发展的世界领导者之一。它拥有丰富的实践知识（也包括自由空间QKD实验），希望能为该项目做出贡献。特别是，UoB将合作开发探测器技术，并提供探测器表征设施，提供快速和慢速驱动电子设备的组合，所有这些都与QKD系统和现场实验的专业知识相结合。
