摘要

氮空位中心系综由于其矢量磁强计能力、室温下的可部署性以及简单的光学初始化和读出，是量子传感器的优秀候选者。这项工作描述了在没有施加静态磁场的情况下控制单晶金刚石中NV系综的所有四个主轴系统（P.A.S.）所需的工程和表征方法。圆偏振微波能够在（100）金刚石中利用自旋锁定实验和使用最优控制理论（OCT）的集体控制进行任意同时控制。这些技术可以进一步改进和集成，以使用所有四个P.A.S.系统实现基于NV的高灵敏度量子传感器件。

Optimal control theory techniques for nitrogen vacancy ensembles in single crystal diamond

Nitrogen vacancy centre ensembles are excellent candidates for quantum sensors due to their vector magnetometry capabilities, deployability at room temperature and simple optical initialization and readout. This work describes the engineering and characterization methods required to control all four principle axis systems (P.A.S.) of NV ensembles in a single crystal diamond without an applied static magnetic field. Circularly polarized microwaves enable arbitrary simultaneous control with spin-locking experiments and collective control using optimal control theory (OCT) in a (100) diamond. These techniques may be further improved and integrated to realize high-sensitivity NV-based quantum sensing devices using all four P.A.S. systems.
