Quantum technologies are a core asset in the UK industrial strategy. They will secure the digital world, see where current cameras cannot, and underpin new drugs, thanks to quantum computers solving currently intractable calculations. In collaboration with the Universities and Research Centres, UK high-tech industries are working on translating them from scientific concepts to available technologies, products, and capabilities. To support this challenge, more than £1Billion has been committed in both Government and Industry funding. Photonics is one of the sectors leading the development and deployment of quantum technologies.Light can carry quantum-secured communications, measure faint signal such as gravitational waves, and solve quantum algorithms. Photonics-based quantum technologies are either required to measure single photons one at a time (single-photon detectors) or to record continuous quantum light signals (proportional detectors) with minimal losses to retain the signatures that make them different from classical light. Here we address this second approach to quantum optical technologies. Today, applications based on such measurement schemes are limited, and detectors are home-built by researchers, often at significant cost in time and monetary. With this project, we join the expertise and capabilities of Bay Photonics (optical packaging and optoelectronics), RedWave Labs (electronics), the experience and resources of the Centre for Process Innovation (photonic applications) and of research teams at the Universities of Strathclyde and Glasgow (quantum sources, low-noise electronics, quantum metrology) to design, build and test a prototype of a quantum sensor able to address this gap in the market and supply chain. We aim to provide the first commercial solution for measuring quantum states of light composed of thousands to several billion photons. The engagement of the Centre for Process Innovation and the University teams will, on the one hand, contribute to the design of the product, and on the other, serve as an end-user test for the developed technology. The outcome of this endeavour will be a versatile solution for the high sensitivity measurements empowering quantum metrology and some of the most advanced concepts of quantum computing.

量子技术是英国产业战略的核心资产。由于量子计算机解决了目前棘手的计算问题，它们将保护数字世界，看到当前相机无法看到的地方，并支持新药物。英国高科技产业正在与大学和研究中心合作，致力于将科学概念转化为可用的技术、产品和能力。为了支持这一挑战，政府和行业已承诺提供超过 10 亿英镑的资金。光子学是引领量子技术发展和部署的领域之一。光可以承载量子安全通信、测量引力波等微弱信号以及解决量子算法。基于光子学的量子技术要么需要一次测量一个光子（单光子探测器），要么以最小的损失记录连续的量子光信号（比例探测器），以保留使其与经典光不同的特征。在这里，我们讨论量子光学技术的第二种方法。如今，基于此类测量方案的应用受到限制，并且探测器是由研究人员自制的，通常需要花费大量时间和金钱。通过这个项目，我们结合了 Bay Photonics（光学封装和光电子学）、RedWave Labs（电子学）的专业知识和能力、工艺创新中心（光子应用）以及斯特拉斯克莱德大学和格拉斯哥大学研究团队（量子源、低噪声电子学、量子计量学）的经验和资源，设计、构建和测试量子传感器原型 能够解决市场和供应链中的这一差距。我们的目标是提供第一个商业解决方案来测量由数千到数十亿光子组成的光的量子态。工艺创新中心和大学团队的参与一方面将有助于产品的设计，另一方面将作为所开发技术的最终用户测试。这项努力的成果将是一个多功能的高灵敏度测量解决方案，为量子计量学和一些最先进的量子计算概念提供支持。
