论文摘要
Diamond中的一个氮呈（NV）中心是固态量子磁力计的主要候选者，能够检测纳米级核磁共振（NMR）的单个核自旋。尽管如此，许多化学家和生物学家的NV磁力计仍然不太容易使用，因为其实验性设置和操作原理与常规NMR截然不同。在这里，我们设计，构建和操作一个紧凑型桌面系统，用于使用单个NV中心，主要由市售的光学组件和电子设备构建。我们表明，我们的设置可以实施最新的量子传感协议，以检测钻石中的单个$^{13} $ c核自旋以及其相互作用参数的表征，以及检测钻石表面上质子核旋转的小集合。本文提供了有关设置和实验程序的细节的广泛讨论，我们的系统将由以前从未在NV中心工作的人重现。
A single nitrogen-vacancy (NV) center in diamond is a prime candidate for a solid-state quantum magnetometer capable of detecting single nuclear spins with prospective application to nuclear magnetic resonance (NMR) at the nanoscale. Nonetheless, an NV magnetometer is still less accessible to many chemists and biologists, as its experimental setup and operational principle are starkly different from those of conventional NMR. Here, we design, construct, and operate a compact tabletop-sized system for quantum sensing with a single NV center, built primarily from commercially available optical components and electronics. We show that our setup can implement state-of-the-art quantum sensing protocols that enable the detection of single $^{13}$C nuclear spins in diamond and the characterization of their interaction parameters, as well as the detection of a small ensemble of proton nuclear spins on the diamond surface. This article providing extensive discussions on the details of the setup and the experimental procedures, our system will be reproducible by those who have not worked on the NV centers previously.
