Single-photon detection is the ability to capture the single quantum of light and is rapidly emerging as the critical capability for numerous emerging quantum technologies, as well as a range of new low-light sensing applications. This International Centre-to-Centre Collaboration proposal links three centres of excellence in quantum photonics to produce a collaboration designed to yield sustained world-class research in the field by combining their complementary expertise. The teams at the Jet Propulsion Laboratory (JPL) working with academic partners at the California Institute of Technology (Caltech) have made significant advances in the field of superconducting nanowire optical detectors in recent years, providing world-class temporal performance (> 5 times better than previously) and the largest format detector arrays yet demonstrated. The link to Heriot-Watt University offers a unique opportunity to use these state-of-the-art detectors in emerging quantum technology application areas such as single-photon and quantum-enhanced LIDAR, free-space and satellite-based quantum communications and in the use of quantum entanglement in ultra-high dimensional quantum imaging and communications. This EPSRC International Centre-to-Centre Collaboration affords a rare opportunity to enhance several world-leading research strands at Heriot-Watt, and make a significant, complementary and sustained contribution to major UK collaborative research initiatives, particularly the EPSRC SPEXS Programme Grant and the EPSRC Quantum Technology Hub network, strongly in line with UK research priorities.

单光子检测是捕获单个量子光的能力，并迅速成为众多新兴量子技术的关键能力，以及一系列新的低光传感应用。这项国际中心合作的合作提案将量子光子学的三个卓越中心联系起来，以结合其互补专业知识来产生旨在在该领域持续的世界一流研究的合作。近年来，与加利福尼亚理工学院（CALTECH）的学术合作伙伴合作的JET推进实验室（JPL）的团队在近年来在超导纳米线光学探测器的领域取得了重大进步，提供了世界一流的暂时性性能（> 5倍以前），并且是最大的格式检测器阵列。指向Heriot-Watt University的链接提供了一个独特的机会，可以在新兴的量子技术应用领域（如单光子和量子增强的LIDAR，自由空间和基于卫星的量子通信，以及在超高的尺寸量子量子成像和通信中使用量子纠缠中的新兴探测器。这项EPSRC国际至中心的合作为难得的机会增强了Heriot瓦特的几项世界领先的研究链，并对英国主要的协作研究计划做出了重大，互补和持续的贡献，尤其是EPSRC SPEXS计划Grant和EPSRC量子量子技术HUB网络，与UK Reseansion相吻合，与EPSRC量子技术HUB网络有关。
