2016年8月16日1时40分,我国在酒泉卫星发射中心用长征二号丁运载火箭成功将世界首颗量子科学实验卫星“墨子号”发射升空。这将使我国在世界上首次实现卫星和地面之间的量子通信,构建天地一体化的量子保密通信与科学实验体系。量子通信是指利用量子纠缠效应进行信息传递的一种新型的通讯方式,是近20年发展起来的新型交叉学科,是量子论和信息论相结合的新的 At 1640 hours on August 16, 2016, China successfully launched the world's first quantum scientific experimental satellite “Mozi” in the Jiuquan Satellite Launch Center with the launch of the Long March No.2 carrier rocket. This will enable China for the first time in the world to realize the quantum communication between the satellite and the ground and to build a heaven-earth integrated quantum confidential communication and scientific experiment system. Quantum communication refers to a new type of communication that uses quantum entanglement to transmit information. It is a new type of interdisciplinary developed in recent 20 years. It is a new combination of quantum theory and information theory
