论文摘要
在钻石中使用氮存道中心来测量具有前所未有的灵敏度的纳米级磁场的可能性是量子传感的最重要成就之一。在这里，我们提出了一种创新的实验设置，显示出具有与最先进的ODMR协议相当的灵敏度，如果考虑到感应量。该设备允许在生物样品（例如单个细胞）中进行磁传感，因为它的特征是较小的感应体积和完整的生物兼容性。研究了不同光学功能的灵敏度，以将此技术扩展到细胞间尺度。
The possibility of using Nitrogen-vacancy centers in diamonds to measure nanoscale magnetic fields with unprecedented sensitivity is one of the most significant achievements of quantum sensing. Here we present an innovative experimental set-up, showing an achieved sensitivity comparable to the state of the art ODMR protocols if the sensing volume is taken into account. The apparatus allows magnetic sensing in biological samples such as individual cells, as it is characterized by a small sensing volume and full bio-compatibility. The sensitivity at different optical powers is studied to extend this technique to the intercellular scale.
