论文摘要
钻石中带负电荷的氮呈（NV-）的室温兼容性使其成为大学教学实验室的理想量子系统。在这里，我们描述了NV-中心电子自旋状态的相干控制实验的低成本实验设置。我们在NV-中心的集合上实施了自旋 - 闪烁测量，光学检测的磁共振，RABI振荡和动态解耦序列。执行这些实验中的每一个所需的相对较短的时间（<10分钟），证明了在教学实验室中设置的可行性。学习成果包括对量子自旋系统，磁共振，旋转框架，BLOCH球体和脉冲序列发展的基本了解。
The room temperature compatibility of the negatively-charged nitrogen-vacancy (NV-) in diamond makes it the ideal quantum system for a university teaching lab. Here, we describe a low-cost experimental setup for coherent control experiments on the electronic spin state of the NV- center. We implement spin-relaxation measurements, optically-detected magnetic resonance, Rabi oscillations, and dynamical decoupling sequences on an ensemble of NV- centers. The relatively short times required to perform each of these experiments (<10 minutes) demonstrate the feasibility of the setup in a teaching lab. Learning outcomes include basic understanding of quantum spin systems, magnetic resonance, the rotating frame, Bloch spheres, and pulse sequence development.
