PHYSICISTS HAVE SUCCEEDED IN TELEPORTING

 

Physicists at the Université de Genève (UNIGE) have succeeded in teleporting the quantum state of a photon to a crystal over 25 kilometers of optical fiber.

The experiment, carried out in the laboratory of Prof. Nicolas Gisin, constitutes a first, and pulverizes the previous record of six kilometers achieved 10 years ago by the same UNIGE team. 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. The results obtained by Félix Bussières and his colleagues are reported in the latest edition of Nature Photonics.
