This project aims to harness the ability to control the fundamental interactions which limit the precision of a diamond quantum sensor, enabling more sensitive magnetometry. Quantum sensors are unveiling new insights into nano-scale phenomena. Single atom defects in diamonds have been at the forefront of this revolution in nano-scale sensor technology. A unique capability, spinning diamond quantum sensors at up to 500,000 rpm, fast enough that quantum properties of the defects are preserved during a cycle has been established. This project will address the long-standing problem of nano-scale solid-materials characterisation using rotationally-enhanced quantum magnetic resonance spectroscopy.

该项目旨在利用控制限制钻石量子传感器精度的基本相互作用的能力，实现更灵敏的磁测量。量子传感器揭示了对纳米尺度现象的新见解。钻石中的单原子缺陷一直处于这场纳米级传感器技术革命的前沿。已经建立了一种独特的能力，即以高达500,000 rpm的速度旋转钻石量子传感器，其速度足以使缺陷的量子属性在一个周期内保持不变。这个项目将解决使用旋转增强量子磁共振光谱表征纳米级固体材料的长期存在的问题。
