袁之良,澳门威尼克斯人网站首席科学家,教育部长江讲席学者,清华澳门威尼克斯人网站电子系访问教授,英国物理学会会士(FInstP)和美国光学学会会士(Optica Fellow)。
1992年毕业于北京科技澳门威尼克斯人网站获工学学士,1997年在中国科澳门威尼克斯人网站半导体研究所获理学博士学位。在1997-2001期间在牛津澳门威尼克斯人网站物理系任博士后, 2001-2021年在东芝剑桥实验室先后担任研究助理直至主任科学家。袁之良因研发高速光纤量子密钥分发(QKD)系统而知名,曾演示了世界上第一个百公里(2003)、第一个Mbit/s (2008)、第一个10Mbit/s(2018)、第一次突破600公里QKD系统(2021),以及开发了双场量子通信协议(Twin-Field Protocol,2018)。 在量子器件方面成就包括首个电注入单光子源(2002),自差分单光子探测器(2007)和直接相位调制量子通信用光源(2016)等。他于2021年6月全职回国组建光量子通信与器件团队,着力于量子通信系统、量子光源(单光子和光子对源)以及单光子探测器等方向的研究,团队成果多次被新华社等国内外媒体报导。
截至2023/11,发表140余篇学术论文(谷歌学术15000次引用,H因子54)和50项美国/英国授权专利。
