Physicists at the University of Geneva (UNIGE) ( http://cms.unige.ch/gap/quantum/wiki/research:quantum_communication:teleportation ) have succeeded in teleporting the quantum state of a photon to a crystal over 25 kilometres of optical fibre. The experiment, carried out in the laboratory of Professor Nicolas Gisin, constitutes a first, and simply pulverises the previous record of 6 kilometres achieved ten 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.

How is the distance relevant to the gain in understanding? Is there any serious doubt it will work in longer distances? Or is it more of practical relevance, to hold the record to secure future funding? (Or - less cynical, - to apply it for quantum cryptography one day?)

I'd like to see this working over a larger distance because it would allow quantum key exchange between data centers, between a data center and a user and between users [soylentnews.org].
