A team of physicists at the University of Science and Technology of China in Hefei has teleported the quantum state of a photon from a high-altitude ground station in Tibet to a satellite 1400km away.
The quantum state was received by China’s Quantum Experiments at Space Scale (QUESS) satellite, which cost $100 million.
As Physics World reports, the process involves creating photons that are quantum-mechanically entangled for transmission.
