Chinese researchers have created a system that quantifies quantum communications over thousands of kilometers. A technical and strategic feat of first importance.
Among the dates that have marked the history of the Internet, it may be necessary to remember September 29, 2017 as the beginning of a new Internet, a "quantum Internet" where data flows are inviolable and can no longer be spied. That day, Chinese and Austrian researchers for the first time succeeded in establishing intercontinental communication, quantum-coded, through a satellite in low Earth orbit. Scientists based in Graz and Xinglong exchanged images and videoconferenced for 75 minutes, while being separated by ... 7600 km. In June 2017, Chinese researchers had already reached a distance of 1200 km. In the space of a few months, the distance has been multiplied by 6.
