2023-现在，物理所研究员。

主要研究方向：

(1) 量子计算: 量子计算利用物理系统的量子特性，如量子叠加态和纠缠态，来解决特定的计算问题。量子计算是当前物理和信息科学中最热门的研究领域之一，学术界和业界均寄予厚望。量子计算的快速发展刷新着我们对信息处理方式和处理能力的预期，也不断加深着我们对量子力学基本规律的认识。我们的研究以可拓展量子计算为远期目标，通过发展和优化固体中自旋量子比特的制备，操控和测量技术，探索量子计算和量子信息相关的物理问题。
(2) 量子传感：为实现量子计算而发展起来的量子调控技术，也是研究微观物质世界的得力工具，量子传感应运而生。我们以金刚石氮空位中心自旋为纳米尺度探针，利用其自旋量子态对周围环境极其敏感的机制，构建高灵敏的量子传感探测方案，并应用到凝聚态物理、材料科学、清洁能源、生命科学等领域前沿问题的研究中。量子传感和量子计算相辅相成，既有深刻的物理问题，也有广阔的应用前景。近期进展见综述文章《极端条件下的金刚石自旋量子传感》

过去的主要工作及获得的成果：

课题组主要进行金刚石氮空位中心量子计算和量子传感实验研究，专注于实现量子计算的关键物理问题，并将自旋量子传感应用于凝聚态物理前沿科学问题研究中。基于自主搭建的多套光磁共振实验平台，发展了完备的金刚石氮空位中心自旋量子调控技术，取得了系列创新成果。量子计算方面，用动力学解耦实现了核自旋的单发读出和普适量子逻辑门操作；用动态核自旋极化延长了中心自旋相干时间并在室温观测到可控的量子涨落效应。自旋量子传感方面，实现了多种临界效应加强的复合量子传感器，将纳米尺度测温灵敏度提升了两个量级；发展了高温和高压极端条件下的自旋量子相干操控和原位磁性测量方案，率先将金刚石氮空位中心量子调控工作区间提升至1000 K高温、以及140 GPa高压等极端条件下，极大地拓展了自旋量子传感的应用范围。
