China Has Teleported An Object Into Space

On July 11th 2017, scientists from the University of Science and Technology of China announced that they have successfully teleported an object from earth into space. In a paper posted to the Cornell University Library, the leader of the team, Professor Chao-Yang Lu said, "Space-scale teleportation can be realized and is expected to play a key role in the future distributed quantum internet."

The experiment involved the phenomenon known as quantum entanglement. In quantum entanglement, when two or more particles interact with one another they become part of a system where the state of one particle can be instantaneously known by the other, even if they are separated by extreme distances. The Chinese researchers were able to establish an ultra long distance up link to an orbiting satellite.

The researchers used a brand new satellite that was launched in 2016 using a Long March Rocket.
The photons in question were beamed from a ground station in Ngari Tibet, up to China's Micius satellite, which was orbiting the earth at a distance of 311 miles. The satellite's sensitive photon receiver detected the states of many single photons, which were part of entangled pairs, that were fired from the ground. The researchers were successful in 900 cases.
