金刚石中的单个氮空位（NV）中心是固态量子磁力计的主要候选者，该磁力计能够检测单个核自旋，并有望应用于纳米级核磁共振（NMR）。尽管如此，对于许多化学家和生物学家来说，NV 磁力计仍然不太容易接触到，因为它的实验设置和操作原理与传统 NMR 截然不同。在这里，我们设计、构建和操作一个紧凑的桌面大小的量子传感系统，具有单个 NV 中心，主要由商用光学元件和电子器件构建。我们表明，我们的装置可以实现最先进的量子传感协议，能够检测金刚石中的单个 $^{13}$C 核自旋及其相互作用参数的表征，以及检测金刚石表面上的质子核自旋的小集合。本文对设置和实验程序的细节进行了广泛的讨论，那些以前没有在 NV 中心工作过的人可以复制我们的系统。
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.
