主要从事集成化量子保密通信网络及光场调控技术研究。
利用集成高性能量子编解码芯片实现高安全等级的大规模量子网络技术。量子保密通信利用量子力学基本原理实现不依赖于计算复杂度的安全通信，是保障国家信息安全的战略技术。集成化量子芯片在实现大规模、高性能量子编解码、缩小设备体积和降低成本方面具有显著优势，因此集成化量子芯片是实现量子保密通信技术大规模实用化的重要基础。我们致力于自主开发量子编解码芯片，发展实用化光电封装技术，并构建光电一体化集成量子保密通信系统和大规模量子网络。近期主要进展：（1）基于集成光频梳技术实现了大规模广播式量子密钥分发（quantum key distribution, QKD）[Laser & Photonics Reviews 14, 1900190 (2020)]，（2）发展集成克尔光频梳的独立锁定技术并实现了百通道级大规模双光子干涉（Hong-Ou Mandel Interference）[Science Advances 11, eadq8982 (2025)]，（3）研制5GHz工作频率的高性能集成光子编码芯片，实现了1Mbps@150km的高码率远距离QKD（Laser & Photonics Reviews e03250 (2026)；（4）构建了大规模集成化测量设备无关全连接量子网络（arXiv2512.17318 (2025)）。
利用量子技术实现量子增强的安全时频传递。时频是现代科学和国计民生的基础，时频传递是实现异地时钟协同的关键技术。因此时频传递的安全关乎国家安全，是重要的战略前沿。我们的目标是基于量子安全技术实现高精度时频传递，构建可认证的量子安全时频传递。近期主要进展：合作实现了高精度时频传递和QKD融合系统（Journal of Lightwave Technology 44, 2256–2264 (2026)）。
基于大规模集成光子学技术发展高性能光场调控器件。光场调控是光学及其广袤应用的基础技术，已经成为多个科学领域的的基础性技术，如光镊（量子计算、生物医学）、光学成像、光学雷达等。我们的远景蓝图是发展高速光场调控技术，将基于该技术的科学研究推向全新层面。近期主要进展：发展光场调控技术，构建了动态散射信道的安全量子链路（Science China Information Sciences 67, 142503 (2024)），开发数字孪生光场相互作用模型实现光场畸变的单次曝光补偿（Laser & Photonics Reviews e01641 (2025)），为复杂信道高效光场传输和量子通信提供了关键技术。
