New long distance quantum teleportation system ‘extremely reliable’

A new milestone has been reached in the development of a practical quantum teleportation system — researchers have for the first time succeeded in the teleportation of information between two separate clouds of gas atoms, over long-distances. And not just once, the method is apparently already extremely reliable — working every single time that it’s been attempted.

It’s been possible for quite some time now to “teleport” information on the quantum level from light to light. And a couple of years back, the same researchers who reached this recent milestone were able to teleport information between between light and gas atoms for the first time. But this new achievement takes that a step further — achieving a very reliable means of gas to gas quantum teleportation over long-distances.

“It is a very important step for quantum information research to have achieved such stable results that every attempt will succeed,” says Eugene Polzik, professor and head of the research center Quantop at the Niels Bohr Institute at the University of Copenhagen.
