Physicists in Switzerland set distance record 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.

It showed that “the quantum state of a photon can be maintained while transporting it into a crystal without the two coming directly into contact,” the UNIGE researchers said in a statement.

Quantum teleportation touches on the theory of how atomic particles behave when pairs of them are “entangled” in a quantum state and start to respond like joined twins, even at a distance.

1. Makes me hope that David Deutsch

writes another book, although I know he's not driven by experimental results so much as advances in theory.
