全球首颗量子卫星"墨子号"在轨测试顺利

 　　The world's first quantum satellite is currently in the middle of in-orbit testing, and will carry out additional scientific tests after November, the Chinese Academy of Sciences (CAS) announced on Oct. 12.

　　根据中科院10月12日公布的消息，全球首颗量子卫星目前正在进行在轨测试，将在11月份之后进行其他科学测试。

　　Nicknamed "Micius," the satellite, Quantum Experiments at Space Scale (QUESS), was launched in China in August.

　　这一名为"墨子号"的空间尺度量子科学实验卫星于今年8月在中国发射升空。

　　"QUESS has three missions to fulfill¹, which are the launch into orbit, in-orbit testing and scientific experiments. Currently, QUESS has entered the second stage, and has completed two tests - of the satellite platform and the payload. Tests of satellite-ground links are now underway," said Pan Jianwei, chief scientist behind the quantum communication satellite project, during an interview with the Beijing Times.

　　在接受《新京报》采访时，量子通讯卫星项目首席科学家潘建伟表示："墨子号共有三个任务要完成，分别是进入轨道、进行在轨测试和进行科学实验。到目前为止，该卫星已经进入了第二阶段，并且完成了两项测试--分别对卫星平台和有效荷载进行了测试。卫星和地面的连接测试目前正在进行中。"

　　According to reports, the battery packs of the satellite are functional², and the success rate of its remote control has reached 100 percent.

　　据报道，该卫星的电池组运转正常，遥控成功率达到了100%。

　　The satellite has successfully tracked all ground stations with satisfactory accuracy.

　　此外，"墨子号"已经成功地追踪到了所有地面站点，精确度也很令人满意。

　　"The satellite has also established three types of satellite-ground links, which has laid a foundation for QUESS scientific missions. We have been adjusting and optimizing³ parameters⁴, accumulating data for future research," Pan said.

　　潘建伟表示："墨子号建立起了三种卫星-地面连接线路，这为空间尺度量子实验室科学任务奠定了基础。我们一直在调整和优化参数，为以后的研究积累数据。"

　　Quantum communication boasts ultra-high security, as a quantum photon can neither be separated nor duplicated. It is therefore impossible to wiretap, intercept⁵ or crack the information transmitted through it.

　　量子通讯具有超高的安全性，因为量子态的光子既不能被分离也不能被复制。因此，不可能对通过量子通讯传输的信息进行窃听、拦截和破解。

　　QUESS, as planned, will also beam entangled⁶ photons to two Earth stations, 1,200 kilometers apart, in a move to test quantum entanglement⁷ over a greater distance.

　　按照计划，墨子号将把一对纠缠的光子分别发送到相距1200公里的两个站点，从而测试更远距离上的量子纠缠。

　　It will additionally test quantum teleportation with a ground station in Ali, Tibet, the Xinhua News Agency reported.

　　据新华社报道，墨子号还将和西藏阿里的一个底面站点进行量子瞬间传输测试。
