论文摘要
近年来，由于其电子自旋特性，钻石中的氮呈（NV）颜色中心已成为极好的固态量子传感器。特别是为了简单的光学初始化和检测，以及它们在室温下非常大的自旋连贯性。许多研究报告了它们用于感应温度，应变，电场和主要是磁场的用途。在这里，我们使用光学成像协议与简单依赖于常规CCD相机的微波脉冲相结合的光学成像协议来展示如何在Ultra Pure Diamond中建立NV中心集合的电子自旋相干性的二维图。
In recent years, nitrogen-vacancy (NV) color centers in diamond have become excellent solid-state quantum sensors due to their electronic spin properties. Especially for their easy optical initialization and detection, together with their very large spin coherence at room temperature. Many studies have reported their use for sensing temperature, strain, electric fields, and mainly magnetic fields. Here, we show how to build a two-dimensional map of the electronic spin coherence of an ensemble of NV centers in ultra-pure diamond, using an optical imaging protocol combined with microwave pulses relying simply on a regular CCD camera.
