Researchers have been able to teleport information from light to light at a quantum level for several years. In 2006, researchers at the Niels Bohr Institute succeeded in teleporting between light and gas atoms. Now the research group has succeeded in teleporting information between two clouds of gas atoms and to carry out the teleportation not just one or a few times, but successfully every single time. The results are published in the scientific journal, Nature Physics.
"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.
The experiments are conducted in the laboratories of the research group in the basement under the Niels Bohr Institute. There are two glass containers, each containing a cloud of billions of caesium gas atoms. The two glass containers are not connected to each other, but information is teleported from the one glass cloud to the other by means of laser light.
The light is sent into the first glass container and then that strange quantum phenomenon takes place, the light and gas become entangled. The fact that they are entangled means that they have established a quantum link they are synchronized.

(16,230 posts)It seems to be saying that information is being sent via quantum entanglement, but I thought that wasn't possible. Am I missing something here?

(6,278 posts)You just can't use it to send information faster than the speed of light...
which admittedly takes most of the fun out if it

(16,230 posts)I'm having trouble grasping the point of it.
I think the real application is in something like quantum computing. You could transfer the state of a quantum register this way.
And there's always this reason...
