Chinese researchers have teleported a photon from the Gobi desert to a satellite orbiting five hundred kilometres above the earth.

This is achieved through quantum entanglement, a process where two particles react as one with no physical connection between them.

Hooke Professor of Experimental Physics at Oxford University Ian Walmsley tells the World At One how quantum entanglement works and how teleportation could be utilised.

Hey, wasn't I recently arguing with some fellow forum mates about whether or not China could out innovate the US?

Eat crow you chowder-heads.

More specifically, the scientists beamed the quantum state of a photon (information about how it is polarized) into orbit.

Not only did the team set a record for quantum teleportation distance, they also showed that one can build a practical system for long-distance quantum communications. Such a communication system would be impossible to eavesdrop on without alerting the users, which would make online communications much more secure.

Experiments like this have been done before, but Howard Wiseman, director of the Center for Quantum Dynamics at Griffith University in Brisbane, Australia, told Live Science in an email that this one expands the possibilities for the technology.

"This is much more difficult, because it is to a rapidly moving target, and you have your quantum detectors way out in space where they have to work without anyone fiddling with them," he said. "It is a big step towards global-scale quantum communication."

I wonder if the distance issue is even an issue. It probably doesn't matter with respect to entanglement.
