Quantum technology initiative is focused on bringing quantum sensors and quantum devices to market and end users. Quantum Sensors offer unquestioned performance advantages in sensitivity and some steps have been made at making more compact systems. But for genuine and widespread applications substantial improvements need to be made in size, weight and power ('SWAP') and ruggedness of these systems. A stable laser is the bedrock for quantum quantum sensors for timing, gravity and magnetic field. They are also the key to secure communication, quantum computation and quantum imaging. In addition to SWAP, such systems need to encompass the wavelength ranges, which are not so easily accessible today. In this project, we aim to develop a laser platform matching the optical performance of current commercial lasers (e.g. Ti:S laser from M2 and Coherent) in a footprint but with a price point comparable to the external-cavity diode laser (ECDL). We plan to demonstrate that such a platform can operate on many otherwise difficult-to-access but crucial lines. Such a development will be a critical step on the road to the translation of QT from the research community to the defence, space and consumer market. In the short term, economic opportunity will arise from the supply chain building activities, delivering novel world leading underpinning technologies. The aimed laser platform will leap frog us in the exploitation of global QT research. The research groups world wide often dream of having turn-key systems. In the medium term, the UK will become the supplier of choice for early low-volume, high-value applications of QT (finance, space) and in the long- term we will be ideally placed to exploit the inevitable transition of QT to the consumer market. The work done in the project will also have a tangle impact on the space sector. In brief, this project will bring reduction in volume, power, size and cost by over an order of magnitude and this will done without losing their performance and robustness. These components are enormously critical, thereby leap frogging the UK QT development and commercialisation.

量子技术计划的重点是将量子传感器和量子设备推向市场和最终用户。量子传感器在灵敏度方面具有无可争议的性能优势，并且在制造更紧凑的系统方面已经采取了一些措施。但为了真正广泛的应用，需要在这些系统的尺寸、重量和功率（“SWAP”）以及耐用性方面进行重大改进。稳定的激光器是用于定时、重力和磁场的量子传感器的基石。它们也是安全通信、量子计算和量子成像的关键。除了 SWAP 之外，此类系统还需要涵盖当今不太容易获得的波长范围。在这个项目中，我们的目标是开发一个与当前商用激光器（例如 M2 和相干公司的 Ti:S 激光器）的光学性能相匹配的激光器平台，其占用空间小，但价格与外腔二极管激光器 (ECDL) 相当。我们计划证明这样的平台可以在许多原本难以访问但至关重要的线路上运行。这样的发展将是 QT 从研究界向国防、太空和消费市场转化的关键一步。短期内，经济机会将来自供应链建设活动，提供世界领先的新颖基础技术。目标激光平台将在全球 QT 研究的开发中超越我们。世界各地的研究小组经常梦想拥有交钥匙系统。从中期来看，英国将成为 QT（金融、太空）早期小批量、高价值应用的首选供应商，从长远来看，我们将处于有利位置，利用 QT 向消费市场不可避免的过渡。该项目所做的工作也将对航天领域产生复杂​​的影响。简而言之，该项目将导致体积、功耗、尺寸和成本减少一个数量级以上，并且不会损失其性能和稳健性。这些组件非常关键，从而超越了英国 QT 的开发和商业化。
