Chinese researchers in the Tibetan mountains have, for the first time, beamed ‘entangled’ particles of light between a satellite and the ground and used ‘spooky’ quantum physics in which the particles can instantly share their information despite being separated by over 1,200km.
It sounds like something out of Star Trek, but maybe something out of James Bond is more accurate. That is because what this is actually about isn’t teleportation, as it is popularly understood, but secret codes, communications security and what the researchers have called the creation of a “quantum internet.”
And along the way they have also proved some frankly weird physics that challenges our commonsense.
