Physicists Beat the Distance Record for Teleporting Light Into Matter


A team of physicists at the University of Geneva (UNIGE) has for the first time demonstrated quantum teleportation over a large distance between particles of light and particles of matter. Spanning 25 kilometers of optical fiber, the researchers successfully transported the quantum state of photon particles to the massive particles of a crystal. 

The current distance record for quantum teleportation still stands at 143 kilometers. That was achieved last year in an experimental setup bridging two Canary islands with high-energy beams of light. The crucial distinction is that the Canary Islands experiment and most other such experiments teleport between light particles and other light particles, rather than the light particles into massive particles of the Geneva scheme.
