Teleporting the internet

Scientists teleport particle into space in major breakthrough for quantum physics

Scientists have successfully teleported something into space for the first time ever.

The experiment saw Chinese scientists send a photon up away from Earth, further than ever before.

Teleportation of this kind uses the bizarre effects of quantum entanglement, rather than physically hurling the object itself over distances. Instead it transfers the information about a photon to another point in space – creating a faithful replication of the object.

It marks the first ever time that effect has been tested over long distances. The success could bring with it a whole range of uses – including a quantum internet that connects different parts of the world at seemingly impossible speed.

Until now, experiments had been restricted to short distances because of problems with the wires or signals that would carry the information.

"This work establishes the first ground-to-satellite up-link for faithful and ultra-long-distance quantum teleportation, an essential step toward global-scale quantum internet," the scientists write in their paper, which has been published online.
