SLAM - Squeezed Light quAntum MEMS Gravimeter

“格拉斯哥大学的工作已经在弹簧上采用了硅制造的质量，该弹簧使用相同的微机电系统（MEMS）技术制造，以确定所有智能手机中的陀螺仪的方向，并将灵敏度提高了5000倍。这种MEMS重力仪有可能用于寻找新的石油和天然气研究，快速发现地下设施，从而减少道路工程，并为火山爆发提供早期预警。该项目旨在提供一种具有相关光子对的量子压缩光源，可用于测量MEMS重力仪的输出，将灵敏度提高到40倍。该项目涉及开发一种光电探测器，可以探测单光子，也可以应用于测距（通过反射光子并计时它们的返回来确定物体的距离），一个关键目标是确保英国供应链使用IQE提供商业锗硅外延单光子探测器和Optocap生产芯片，规模的真空封装与光纤接入，这是必要的组成部分，为MEMS重力仪。"

"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 gravimeter."
