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.
Nicknamed "Micius
" the satellite
Quantum Experiments at Space Scale (QUESS)
was launched in China in August.
"QUESS has three missions to fulfill
which are the launch into orbit
in-orbit testing and scientific experiments. Currently
QUESS has entered the second stage
and has pleted o tests - of the satellite platform and the payload. Tests of satellite-ground links are now underway
" said Pan Jianwei
chief scientist behind the quantum munication 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 functional
and the success rate of its remote control has reached 100 percent.
The satellite has successfully tracked all ground stations with satisfactory accuracy.
"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 optimizing parameters
accumulating data for future research
" Pan said.
Quantum munication boasts ultra-high security
as a quantum photon can neither be separated nor duplicated. It is therefore impossible to wiretap
intercept or crack the information transmitted through it.
QUESS
as planned
will also beam entangled photons to o Earth stations
1
200 kilometers apart
in a move to test quantum entanglement over a greater distance.
It will additionally test quantum teleportation with a ground station in Ali
Tibet
