| 内容記述 | The nitrogen-vacancy center in diamond is an exquisite solid-state sensor based upon quantum nature. Numerous studies have shown that dynamical decoupling, such as an XY8 sequence, provides us a high sensitivity for an oscillating magnetic field parametrized by amplitude and phase. However, there are some drawbacks. (1) A measurement using XY8 requires a careful adjustment of timings between XY8 sequences and the target signal. (2) The XY8 has an intricate dependence on both parameters, so it is not applicable in a situation that both parameters simultaneously change. (3) It is impossible to measure both parameters simultaneous, and they have to be measured severally. In this study, we present that Qdyne1-3, a quantum-classical hybrid protocol, solves them, consisted of sequential and stroboscopic measurements. The Qdyne does not require a timing adjustment before itself, has an intuitive dependency on both parameters, and let us a simultaneous measurement of both amplitude and phase. Moreover, we implemented it on a widefield of view. The large observation area of widefield modality and the high spatial resolution of NV center pave the way for a tiny-scale inspection by Eddy-current, which established sensors cannot detect. | |||||
