Submission + - Quantum teleportation distance record smashed
Ivan Stepaniuk writes: For the first time, a team of physicists at the Univertisty of Geneva have successfully teleported a quantum state of a photon to a crystal over 25 kilometers away through a fiber optic cable, smashing their own previous record of 6 kilometers, archieved a decade ago. The press release reports:
Passing from light into matter, using teleportation of a photon to a crystal, shows that, in quantum physics, it is not the composition of a particle which is important, but rather its state, since this can exist and persist outside such extreme differences as those which distinguish light from matter.
