On Aug 16, China launched the world's first quantum satellite. Named after the ancient Chinese philosopher and scientist Micius, the satellite's launch was regarded as a big step in building a space-based quantum communication network that would be virtually uncrackable.
Professor LI Chuanfeng and XU Jinshi from Key Laboratory of Quantum Information, University of Science and Technology of China of Chinese Academy of Sciences together with collaborators, have made breakthrough in correlated quantum channels. They experimentally realized bidirectional quantum information transmission in quantum channels each with zero quantum capacity. It leads to a deep understanding of activation phenomenon in noisy quantum channel. The study is published online in Science Advances.
