In China, a quantum teleportation between the cosmos and the Earth was carried out for a distance of more than 1.2 thousand kilometers.

Quantum teleportation was carried out with the help of a pair of satellites and three ground stations, at a distance of approximately 500-2000 kilometers. Between two of these ground stations, the distance was a record 1.2 thousand kilometers.

Quantum teleportation is the transfer of the quantum state of a particle over a distance. For this, a spaced pair of coupled particles is used: according to quantum mechanics, even when removing such particles from each other, they retain information about the state of their partner.
