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.

Faster Than Light communication would be the logical application.

You can't use quantum teleportation for faster-than-light communication. The interesting part of quantum teleportation is that normally you can't put a particle in a specific desired quantum state with only classical interactions. Quantum teleportation is a workaround for that. It could be useful for communication between two quantum computers.

Apparently not [wikipedia.org]. (Although I didn't really understand, why. The article leaves some comforting feeling of dawning understanding- until I think properly about it. It's probably quantum as well, you can either feel you understood or you can try to think about it, but not both at the same time with full intensity.)
