“墨子号”完成基于胶葛的无中继千千米量子失密通讯

宣布时候:2020-06-16来历于:中国迷信手艺大学

中国迷信手艺大学潘建伟及其共事彭承志、印娟等构成的研讨团队,连系牛津大学Artur Ekert、中科院上海手艺物理研讨所王建宇团队、细小卫星立异研讨院、光电手艺研讨所等相干团队,操纵“墨子号”量子迷信尝试卫星在国际上初次完成千千米级基于胶葛的量子密钥散发。该尝试功效不只将以往空中无中继量子失密通讯的空间间隔进步了一个数目级,并且经由进程物理道理确保了即便在卫星被他方节制的极度环境下依然能完成宁静的量子通讯,取得了量子通讯实际操纵的主要冲破。6月15日,研讨团队在国际闻名学术期刊《天然》杂志上在线颁发了题为“基于胶葛的千千米级宁静量子加密(Entanglement-based secure quantum cryptography over 1,120 kilometres)”的研讨论文。《天然》杂志为此特地宣布了题为“基于卫星的远间隔宁静通讯(Quantum physics: Long-range satellite-based secure communications)”的消息稿(Press release)加以推介。
