量子隐形传态

量子遥传（quantum teleportation），又称量子隐形传输、量子隐形传送、量子隐形传态，是一种利用量子缠结来传送量子态至任意距离的技术。 名词翻译可能最早见于 2000 年科学月刊上的文章，因为 tele 字首表示远方的意思。
量子遥传并不会传送任何物质或能量。这样的技术在量子信息与量子计算上相当有帮助。然而，这方式无法传递传统的资讯，因此无法使用在超光速的通讯上面。量子遥传与一般所说的瞬间移动没有关系，量子遥传无法传递系统本身，也无法用来安排分子以在另一端组成物体。
2019年8月18日中国科学技术大学潘建伟、陆朝阳等和奥地利维也纳大学蔡林格(Zeilinger)小组合作，在国际上首次成功实现高维度量子体系的隐形传态。此前的实验中只能完成二维传输，此一突破可以达成任意维度传输，向实用化大幅推进。该研究成果发表于国际权威学术期刊《物理评论快报》(PRL)。
