Long Range Quantum Teleportation

Teleportation: Yes, It’s Finally Here


According to a report by Discovery News, Chinese scientists have managed to ‘teleport” information almost ten miles (16 kilometres) by using what is called “quantum entanglement.”

Beam Me Up, Scotty! Scientists Teleport Info 10 Miles

We may never be able to teleport ourselves "Star Trek"-style, but scientists managed to transmit information a record distance using entangled photons.

THE GIST
  • Scientists manage to teleport information nearly 10 miles with unprecedented precision.
  • The team used quantum entanglement to teleport the information.
  • The feat could lead to a global, impenetrable communication network and powerful quantum computers.

Quantum teleportation achieved over 16 km


a, A birds-eye view of the 16-km free-space quantum teleportation experiment. Charlie sends photon 1 to Alice for BSM. Classical information, including the results of the BSM and the signal for time synchronization, is sent through the free-space channel with photon 2, to Bob, before decoding and triggering of the corresponding unitary transformation. b, Sketch of the experimental system.

The experiments confirm the feasibility of space-based , and represent a giant leap forward in the development of applications.
The paper is available in full online at Nature Photonics.
