A group of Chinese scientists plans to create a quantum space communications system for the first time ever by launching a satellite that could facilitate quantum teleportation of photons between earth and space this June.

rt.com reports..

The aim of the new experiment conducted by a team led by physicist Pan Jian-Wei from the University of Science and Technology of China in Hefei is to see if the quantum property of entanglement extends over record-breaking distances of more than 1,000 kilometers.

This could potentially facilitate super-fast, long-range communications, as well as lead to the creation of unbreakable quantum communication networks. The team also wants to use the world’s first quantum satellite to find out if it is possible to teleport information securely between Earth and space using entangled photons. The launch of the satellite is scheduled for June, the international weekly of science Nature reports.

“In principle, quantum entanglement can exist for any distance. But we want to see if there is some physical limit… we hope to build some sort of macroscopic system in which we can show that the quantum phenomena can still exist,” Pan told Nature, in describing the theoretical premises for the experiment.

The satellite’s first mission would involve establishing a cryptographic communication line between Beijing and Vienna by creating “[the encoding and sharing of a secret cryptographic key using the quantum properties of photons] between a ground station in Beijing and the satellite, and between the satellite and Vienna.”

Scientists then plan to conduct satellite entangled photon quantum teleportation between stations located in the Chinese cities of Delingha and Lijiang or Nanshan, which are separated by more than 1,200 kilometers. The team has already conducted successful tests at a distance of 100 kilometers.
