论文摘要
固态自旋缺陷是各种传感靶标的有希望的量子传感器。这些缺陷中的一些夫妇明显地将宿主材料劳累。我们建议使用这种应变耦合，以通过光学机械诱导的透明度测量测量机械介导的分散式单光旋转读数。令人惊讶的是，钻石中负电荷硅的缺陷的估计测量时间比单光光学荧光读数的数量级要短。我们的方案也可以用于一般参数估计计量学，并且比使用连续位置检测的常规方案具有更高的灵敏度。
Solid-state spin defects are promising quantum sensors for a large variety of sensing targets. Some of these defects couple appreciably to strain in the host material. We propose to use this strain coupling for mechanically-mediated dispersive single-shot spin readout by an optomechanically-induced transparency measurement. Surprisingly, the estimated measurement times for negatively-charged silicon-vacancy defects in diamond are an order of magnitude shorter than those for single-shot optical fluorescence readout. Our scheme can also be used for general parameter-estimation metrology and offers a higher sensitivity than conventional schemes using continuous position detection.
