论文摘要
我们提出了一种依靠绝热性快捷方式以稳健方式在纳米级处实现高频信号的量子检测方法。更具体地说，我们的协议为控制字段提供了量身定制的振幅和频率，首先，这些振幅可以使传感器与高频信号耦合，其次，将传感器耦合到最小化误差，否则会破坏检测过程。为了举例说明该方法，我们将通过氮空位中心量子传感器快速旋转核自旋发出的信号进行了特定。但是，我们的协议直接适用于其他量子设备，例如硅空置中心，锗空位中心或碳化硅硅的分区。
We present a method relying on shortcuts to adiabaticity to achieve quantum detection of high frequency signals at the nanoscale in a robust manner. More specifically, our protocol delivers tailored amplitudes and frequencies for control fields that, firstly, enable the coupling of the sensor with high-frequency signals and, secondly, minimise errors that would otherwise spoil the detection process. To exemplify the method, we particularise to detection of signals emitted by fast-rotating nuclear spins with nitrogen vacancy center quantum sensors. However, our protocol is straightforwardly applicable to other quantum devices such as silicon vacancy centers, germanium vacancy centers, or divacancies in silicon carbide.
