Physicists Make Big Leap In Quantum Teleportation

Physicists in Switzerland said Sunday they had succeeded in teleporting the quantum state of a photon to a crystal, in which information transited from light to matter, over a record distance of 25 kilometres (15.5 miles). The experiment, conducted over optical fibre at the University of Geneva, beat the team's previous record in 2003 of six kilometres (3.7 miles). It showed that "the quantum state of a photon can be maintained while transporting it into a crystal without the two coming directly...
