二、集成光场调控器件和应用

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 20, e01641 (2026)），构建地球同步轨道星地复杂QKD信道链路的动态信道模型（ npj Quantum Information (2026), DOI: 10.1038/s41534-026-01363-3），为复杂信道高效光场传输和量子通信提供了关键技术。

三、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)）。
