- 요약The nitrogen-vacancy (NV) center in diamond is an atom-like point defect that is widely used as a quantum sensor thanks to its unique combination of sensitivity, robustness, and spatial resolution. Despite decades of study, there remain open questions regarding the limits of the NV center's capabilities as a sensor. In this dissertation, I describe results that inform our understanding of the fundamental limits of NV-based sensing, and I introduce a novel method for applying the NV center in practice. In particular, I present experimental measurements of phonon-limited spin relaxation rates within the NV center's ground-state electronic spin triplet as a function of applied magnetic field and temperature. I further present experimental measurements of the temperature dependence of the ground-state zero-field splitting (ZFS). I describe theoretical work to understand the dominant interactions in each of these cases, and I demonstrate analytical models of the temperature dependence of both effects, which could be used more broadly to understand other properties of the NV center and related defects that are rooted in spin-phonon interactions. In addition, I describe an apparatus for parallel NV center measurements which is based on fast, high-fidelity spin- and charge-state manipulations and readout. I present results from experiments conducted using this apparatus to measure up to 108 NV centers in parallel, and I discuss prospects for scaling up the system to measure thousands of NV centers. The apparatus allows spatial correlations in a target field to be detected efficiently and with nanoscale spatial resolution, making it well-suited to probe the correlations that commonly characterize condensed matter systems.
