Introduction

孙启超，2017年在上海交通大学获得博士学位，2012-2017年于中国科学技术大学联合培养，研究方向为光纤量子通信技术；2018年至2021年在德国斯图加特大学第三物理研究所从事量子传感方向的博士后研究工作。

近年来主要学术成果包括：发展了低温扫描单自旋磁力仪技术并应用于固体材料研究，国际首次观测到转角堆叠二维磁性材料中的磁性moiré结构；发展了独立纠缠源干涉技术，国际首次在城域光纤网络上实现了量子隐形传态。在Science（1篇）、Nature Photonics（2篇）、Physical Review Letters（4篇）、Nature Communications（1篇）、Optica（1篇）等国际学术期刊上发表论文近20篇。

目前的主要研究方向是固态自旋量子传感和量子通信技术，致力于实现纳米尺度空间分辨的高灵敏度磁场、电场、温度探测技术，开展在固体材料探测方面的应用研究；实现远距离纠缠态的制备、传输及操纵等量子网络关键技术
