This project will investigate the use of atom interferometry to identify force anomalies created by the presence of dense masses situated behind barriers. Because gravitational fields cannot be screened, it has potential applications as a security screening tool that is complimentary to alternative imaging techniques using electromagnetic or radiographic approaches. The student will theoretically explore the optimal interferometer configurations for force anomaly sensing and extend the operation of existing Imperial atom interferometers to measure the gravitational effect of test masses positioned at known standoff distances. In addition to the interferometry work at Imperial, the student will spend 1 - 3 months of their time at the Atomic Weapons Establishment's (AWE) quantum sensing laboratory. Here, they will learn complimentary electromagnetic imaging technique being developed with a view to combining atom interferometry and conventional sensing methods for future quantum technologies that can improve security.

这个项目将研究使用原子干涉测量法来确定障碍物后面的密集物质所产生的力异常。由于重力场不能被筛选，它具有作为安全筛选工具的潜在应用，该工具与使用电磁或射线照相方法的替代成像技术互补。学生将从理论上探索用于力异常感测的最佳干涉仪配置，并扩展现有帝国原子干涉仪的操作，以测量位于已知距离的测试质量的引力效应。除了在帝国的干涉测量工作，学生将花1 - 3个月的时间在原子武器机构（AWE）的量子传感实验室。在这里，他们将学习正在开发的互补电磁成像技术，以期将原子干涉测量和传统的传感方法结合起来，用于未来的量子技术，从而提高安全性。
