【100公里！#北京科研团队创造量子直接通信距离世界新纪录#】日前，北京量子信息科学研究院、清华大学龙桂鲁教授团队和陆建华教授团队合作，设计和实现了一种相位量子态与时间戳量子态混合编码的量子直接通信新系统，通信距离达到100公里，是当前世界最长的量子直接通信距离。Chinese scientists have realized the world's longest quantum secure direct communication (QSDC) of 100 kilometers, according to a recent study. The study, jointly conducted by a team of scientists from Tsinghua University and the Beijing Academy of Quantum Information Sciences, was published in early April in the journal Light: Science & Applications.
