The quantum geometric phase has long been viewed as an interesting, but somewhat mysterious, feature of quantum mechanics. However, the ability to harness and control geometric phase in individual quantum systems may drive the development of a new class of quantum technologies. This project aims to measure, for the first time, geometric phase due to the macroscopic motion of an atom-scale quantum system, specifically in rotating nitrogen-vacancy defects in diamond. It is expected that these proof-of-principle measurements will provide the basis for the future development and design of new nano-scale quantum gyroscopes and set the foundations for using nano-diamonds as rotational diagnostic tools in a range of important nanoscopic systems.

量子几何相位长期以来一直被视为量子力学的一个有趣但有些神秘的特征。然而，利用和控制单个量子系统中几何相位的能力可能会推动新型量子技术的发展。该项目旨在首次测量由于原子级量子系统的宏观运动而产生的几何相位，特别是金刚石中旋转的氮空位缺陷。预计这些原理验证测量将为新型纳米级量子陀螺仪的未来开发和设计提供基础，并为在一系列重要纳米系统中使用纳米金刚石作为旋转诊断工具奠定基础。
