First Object Teleported from Earth to Orbit

“Back in the 1990s, scientists realized they could use this link to transmit quantum information from one point in the universe to another. The idea is to ‘download’ all the information associated with one photon in one place and transmit it over an entangled link to another photon in another place.

This second photon then takes on the identity of the first. To all intents and purposes, it becomes the first photon. That’s the nature of teleportation and it has been performed many times in labs on Earth…In theory, there should be no maximum distance over which this can be done…

‘We report the first quantum teleportation of independent single-photon qubits from a ground observatory to a low Earth orbit satellite—through an up-link channel— with a distance up to 1400 km,’ says the Chinese team…

‘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,’ says the team.”
