Chinese physicists have managed to teleport photons over 97km employing quantum entanglement. The achievement is a important step in the direction of an ultra-secure communication system that would be immune to eavesdropping.
The group had achieved achievement prior to in 2010 when they managed to teleport a photon 16km. “The productive quantum teleportation over such channel losses in mixture with our large-frequency and substantial-accuracy [aiming] strategy show the feasibility of satellite-based mostly ultra-prolonged-distance quantum teleportation,” said Juan Yin at the University of Science and Technology in Shanghai.
