Work at the University of Glasgow has already taken a silicon fabricated mass on a spring fabricated using the same Micro- Electro Mechancal System (MEMS) technology to the gyroscope in all smart phones that determine orientation and improved the sensitivity by a factor of 5000. This MEMS gravimeter has the potential to be used to search for new oil & gas researches, find buried utilities quickly thereby reducing roadworks and provide an early warning for volcanic eruptions. The project aims to deliver a quantum squeezed light source with pairs of correlated photons that can be used to measure the output of the MEMS gravimeter improve the sensitivity by up to a factor of 40. The project involves developing a photodetector that can detect single photons which also has applications of rangefinding (determining how far away objects are by bouncing photons off them and timing their return) at wavelengths of light that can see through rain, mist and fog.A key objective is to secure a UK supply chain using IQE to deliver commercial Ge on Si epitaxy for single photon detectors and Optocap to produce chip-scale vacuum packages with fibe-optic access which are essential components for the MEMS

格拉斯哥大学的工作已经将采用相同微机电系统 (MEMS) 技术制造的弹簧上的硅质质量应用于所有智能手机中的陀螺仪，确定方向并将灵敏度提高了 5000 倍。 MEMS 重力仪有潜力用于寻找新的石油和天然气研究、快速发现埋藏的公用设施，从而减少道路施工，并为火山爆发提供早期预警。该项目旨在提供具有相关光子对的量子压缩光源，可用于测量 MEMS 重力计的输出，将灵敏度提高多达 40 倍。该项目涉及开发一种可以检测单光子的光电探测器，还具有可透过雨、雾和雾的光波长的测距应用（通过从物体上反射光子并计时其返回来确定物体的距离）。一个关键目标是使用 IQE 确保英国供应链的安全为单光子探测器和 Optocap 提供商业化的硅基硅外延，以生产带有光纤接入的芯片级真空封装，这是 MEMS 的重要组件
