AI总结:

本文提出利用光力诱导透明和自旋-应变耦合实现力学介导的单次自旋读出,在金刚石硅空位缺陷中测量时间比荧光读出短一个数量级,并可用于高灵敏度参数估计计量。

摘要:

固态自旋缺陷是一类极具前景的量子传感器,可用于多种多样的传感目标。其中一些缺陷会与宿主材料中的应变发生显著耦合。我们提出利用这种应变耦合,通过光力诱导透明测量实现力学介导的色散式单次自旋读出。令人惊讶的是,对于金刚石中带负电的硅空位缺陷,估计的测量时间比单次光学荧光读出短一个数量级。我们的方案还可用于一般的参数估计计量,并且相比使用连续位置探测的传统方案具有更高的灵敏度。

英文摘要:

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.
