Atom interferometry is a sensing technique broadly analogous to traditional light-based interferometry methods, where matter waves are interfered with one another rather than light. It offers potential for highly sensitive detection of inertial forces in addition to applications in fundamental science. It is quickly becoming a cornerstone of the wider field of quantum technology. The University of Liverpool currently has an operational atom interferometer. The project will oversee the realization of an upgraded version of this, significantly larger interrogation times with improvements over the original device. An atom interferometer is a complex system and the project will involve prototyping and development of multiple enabling components, including but not limited to compensation of external forces, implementation of large momentum transfer to increase device sensitivity and control software and electronics to allow for alternative measurement paradigms such as phase shear measurement to be employed, drastically reducing the time for a measurement cycle. Atom interferometers are versatile in their applications. The fact that atoms have mass means that unlike their light-based counterparts means atom interferometers can be used to make direct measurements of gravitational forces. This makes them an attractive prospect for potential practical applications such as a new breed of gyroscopes and accelerometers.

原子干涉测量是一种传感技术，与传统的基于光的干涉测量方法大致类似，其中物质波相互干涉而不是光。除了在基础科学中的应用外，它还提供了对惯性力的高灵敏度检测的潜力。它正迅速成为更广泛的量子技术领域的基石。 利物浦大学目前有一台原子干涉仪。该项目将监督实现这一升级版本，大大增加了询问时间，并对原始设备进行了改进。原子干涉仪是一个复杂的系统，该项目将涉及多个使能组件的原型设计和开发，包括但不限于补偿外力，实现大动量转移以提高设备灵敏度，以及控制软件和电子设备，以允许采用其他测量范例，如相位剪切测量，大大减少测量周期的时间。原子干涉仪的应用范围很广。原子具有质量的事实意味着，与基于光的对应物不同，原子干涉仪可以用来直接测量引力。这使得它们在潜在的实际应用中具有诱人的前景，例如新型陀螺仪和加速度计。
