Solid-state spin systems including nitrogen-vacancy (NV) centers in diamond constitute an increasingly favored quantum sensing platform. However, present NV ensemble devices exhibit sensitivities orders of magnitude away from theoretical limits. The sensitivity shortfall both handicaps existing implementations and curtails the envisioned application space. This review analyzes present and proposed approaches to enhance the sensitivity of broadband ensemble-NV-diamond magnetometers. Improvements to the spin dephasing time, the readout fidelity, and the host diamond material properties are identified as the most promising avenues and are investigated extensively. This analysis of sensitivity optimization establishes a foundation to stimulate development of new techniques for enhancing solid-state sensor performance.

NV金刚石磁力计的灵敏度优化

包括金刚石中的氮空位(NV)中心在内的固态自旋系统构成了越来越受欢迎的量子感测平台。但是,当前的NV合奏设备的灵敏度比理论极限高出几个数量级。灵敏度不足既阻碍了现有的实现,又缩小了预期的应用空间。这篇综述分析了当前和提议的方法来增强宽带合奏-NV-金刚石磁力仪的灵敏度。自旋移相时间,读数保真度和主体金刚石材料性能的改进被认为是最有前途的途径,并进行了广泛的研究。灵敏度优化的这一分析为刺激增强固态传感器性能的新技术的发展奠定了基础。
