It’s a highly sensitive photon receiver that can detect the quantum states of single photons fired from the ground. Entanglement, cryptography, and teleportation processes are possible in scientific experiments. Teleportation has become a standard operation in quantum optics labs around the world. In technical terms, a such situation related to a pair locations are described by the same wave function.

The teleportation experiment

Back in the 1990s, scientists realized they could use this link to transmit quantum information from one point in the universe to another. In theory, there should be no maximum distance over which this can be done but practically at this time there are severe limitations, generally under 100 kilometers. So the Chinese experiment was a performence. To perform the experiment, the Chinese team created entangled pairs of photons on the ground at a rate of about 4,000 per second. This is the first time that any object has been teleported from Earth to orbit, and it smashes the record for the longest distance for entanglement.
