GCC - Gravity Cartography Catalyst

长期以来，探测我们周围的世界一直是科学研究的基石，许多传感技术的开发是为了商业用途，而不是纯粹的科学价值。观察地下环境的能力仅限于破坏性的勘探技术，但近年来，商业遥感器已经变得更加普遍。然而，非破坏性方法可能会受到严重阻碍，地面特征可能会被掩盖，振动或电磁干扰可能会完全阻止测量。这些问题从根本上限制了现有的建筑和基础设施监测技术，因为挖掘费用高昂，而且可能无法关闭现场。量子传感技术可以通过精确测量重力来克服这些障碍。通过冷原子干涉测量，铷原子的量子性质与激光束的相位进行比较，检测原子在真空中自由下落的微小变化。这些变化可以用来确定当地的重力加速度，泄露你脚下的空隙，管道，隧道或石油和天然气储备的位置。最近的科学成就证明，原子干涉测量法是地下探测地下隧道或管道等特征的宝贵工具（doi.org/10.1038/s41586-021-04315-3）。实现量子传感器的技术已经存在，并已在该领域得到证明，但它需要商业工程技术才能让那些没有受过高度专业培训的人日常使用。Delta g Limited是一家新的量子初创公司，在利用第二代量子技术方面处于独特的地位，将向最终用户提供世界上第一台商用单按钮重力梯度仪。Delta g为现场测量带来了世界一流的量子重力梯度测量专业知识，并与伯明翰大学和QT Hub for Sensors and Timing建立了直接联系，以提供科学支持。来自多个行业的领导者将作为顾问或分包商参与，以提供关键的项目能力。STL是一家工程咨询公司，在将深度技术量子引入商业领域方面拥有丰富的经验，将提供定制的软件、控制和射频功能。NKT Photonics是世界领先的激光系统和组件制造商，将为GCC系统提供定制的COTS激光引擎。在最初的项目研讨会上，Delta g将展示先前试验的结果，然后将这些结果用作基准，来自多个行业垂直领域的顾问小组将使用这些结果来定义项目的一系列要求和成功标准。

Detecting the world around us has long been a cornerstone of scientific research, with many sensing technologies developed for commercial use rather than purely scientific merit.The ability to view the subterranean environment was limited to destructive exploratory techniques, but in recent years commercial remote sensors have become more widespread. However, nondestructive methods can be severely hindered, ground features can be obscured and vibration or electromagnetic interference can prevent measurements altogether. These issues fundamentally limit the existing technologies for construction and infrastructure monitoring due to costly excavation and site closures which may not be possible. Quantum sensing techniques can overcome these barriers with precision measurements of gravity. Through cold-atom interferometry the quantum nature of a rubidium atom is compared to the phase of a laser beam, detecting very small changes in how the atoms fall freely in a vacuum. These changes can be used to determine the local gravitational acceleration, betraying the location of voids, pipes, tunnels or oil and gas reserves beneath your feet. Recent scientific achievements have proven atom interferometry is an invaluable tool for subsurface detection of features like buried tunnels or pipelines (doi.org/10.1038/s41586-021-04315-3). The technology to make the step to quantum sensors already exists, and has been proven in the field, however it needs commercial engineering techniques to bring it into everyday use by those without highly specialised training. Delta g Limited, a new quantum start-up in a unique position to take advantage of this second-generation quantum technology, will deliver the world's first commercial single button gravity gradiometer into the hands of end-users. Delta g brings world class expertise in quantum gravity gradiometry for field measurements, with direct links to the University of Birmingham and the QT Hub for Sensors and Timing to provide scientific support. Leaders from multiple industries will be involved as advisors or subcontractors to deliver key project capabilities. STL, an engineering consultancy with experience in bringing deep tech quantum to the commercial sphere, will deliver bespoke software, control and RF capabilities. NKT Photonics, a world leading laser system and component manufacturer, will provide a customised COTS laser engine for the GCC system. At an initial project workshop Delta g will present the results of previous trials, these will then be used as a benchmark and a panel of advisors, from across multiple industrial verticals, will use this to define a set of requirements and success criteria for the project.
