Chinese scientists successfully teleport photon from Earth to space
Teleportation has always seemed a far-fetched possibility for mankind, often being reserved only for movies and science-fiction.
Now, the process has become a reality, thanks to quantum physics.

Photons are considered an elementary particle, a result of an electromagnetic radiation such as light.
“Long-distance teleportation has been recognized as a fundamental element in protocols such as large-scale quantum networks and distributed quantum computation,” a representative from the Chinese team told MIT Technology review, as relayed by the news outlet.
“Previous teleportation experiments between distant locations were limited to a distance on the order of 100 kilometers, due to photon loss in optical fibers or terrestrial free-space channels.”

The satellite was initially launched to test various technological building blocks including entanglement, cryptography and teleportation.
Not only was the group able to accomplish the latter; it also set the record for the longest distance for which entanglement has been measured, the report said. Khristian Ibarrola /ra
