摘要:

振荡场的精确光谱分析在许多领域都具有重要的意义。在这里,我们提出了一个实验上可行的方案,使用单量子位传感器测量快速振荡场的频率。通过调用稳定的经典时钟,连续测量之间的信号相位相关性使我们能够以极高的精度提取目标频率。此外,我们将动态解耦技术集成到框架中,以抑制慢环境噪声的影响。我们的框架是可行的各种原子和单固态自旋系统内的国家的最先进的实验能力作为一个通用的工具,量子光谱。

英文摘要:

Precise spectroscopy of oscillating fields plays significant roles in many fields. Here, we propose an experimentally feasible scheme to measure the frequency of a fast-oscillating field using a single-qubit sensor. By invoking a stable classical clock, the signal phase correlations between successive measurements enable us to extract the target frequency with extremely high precision. In addition, we integrate dynamical decoupling technique into the framework to suppress the influence of slow environmental noise. Our framework is feasible with a variety of atomic and single solid-state-spin systems within the state-of-the-art experimental capabilities as a versatile tool for quantum spectroscopy.
