9月29日,世界首条量子保密通信干线——“京沪干线”正式开通;结合“京沪干线”与量子科学实验卫星“墨子号”的天地链路,我国科学家成功实现了洲际量子保密通信。这标志着我国已构建出天地一体化广域量子通信网络雏形,为未来实现覆盖全球的量子保密通信网络迈出了坚实的一步。 On September 29, the world’s first quantum secure communications trunk, the “Beijing-Shanghai Route,” was formally launched. In combination with the world link of the “Beijing-Shanghai Route” and the “Quantum Science Experimental Satellite” “Mozi No.”, China Scientists successfully implemented intercontinental quantum secure communications. This indicates that our country has constructed a prototype of a world-wide intergated wide-area quantum communication network and taken a solid step toward realizing the global coverage of quantum secure communication networks in the future.
