Chinese physicists have managed to teleport photons over 97km using quantum entanglement.
The achievement is a significant step towards an ultra-secure communication system that would be immune to eavesdropping. The team had achieved success before in 2010 when they managed to teleport a photon 16km. "The successful quantum teleportation over such channel losses in combination with our high-frequency and high-accuracy [aiming] technique show the feasibility of satellite-based ultra-long-distance quantum teleportation," said Juan Yin at the University of Science and Technology in Shanghai.
"The idea is not that the physical object is teleported but the information that describes it."
