Project U-Quant: Ultra-low SWaP quantum communication payload for tactical and space applications

QKD为加密密钥的共享提供了一种安全的方法。通过自由空间卫星链路，可以实现远距离密钥共享，并增强全球对量子技术好处的访问。当前最先进的技术具有局限性，例如需要复杂的大型控制系统，易受损失或低生成速率。U-Quant的目标是将具有单光子源和QKD控制系统开发专业知识的合作者聚集在一起，为市场提供低损耗、低swap集成的QKD系统，该系统利用真正量子光源的卓越性能。这一发展将使超紧凑产品制造成为可能，为市场提供适合集成到当前卫星系统中的低成本、真正的量子技术。

QKD provides a secure method for the sharing of encryption keys. Via free-space satellite links, long-distance key sharing can be achieved and global access to the benefits of quantum technologies is enhanced. Current state-of-the-art technology has limitations, such as the need for complex, large control systems, susceptibility to loss, or a low-key generation rate. U-Quant aims to bring together collaborators with expertise in single photon source and QKD control system development to provide the market with a low-loss, low-SWaP integrated QKD system that utilises the superior performance of true quantum light sources. This development will allow ultracompact product manufacturing to take place, providing the market with a low-cost, true-quantum technology that is suitable for integration into current satellite systems.
