In the summer of 2016, Chinese scientists will conduct the world's first experiment to implement quantum teleportation over a distance of more than 1200 kilometers. Reported by Nature News.
For the experiment, scientists plan to launch a satellite in June 2016. Thus, physicists hope to achieve quantum teleportation of particle states between space and ground stations.
At the first stage of the experiments, scientists are going to test the reliability of the cryptographic connection between Beijing and Vienna, which will be mediated by a near-earth satellite.
At the second stage, scientists through a satellite will carry out quantum teleportation of photons between stations in Deling and in Lijiang (or Nanshan). The distance between the points exceeds 1200 kilometers.
Physicists have no doubts about the success of the experiment, since quantum teleportation is defined for any distance. Scientists' plans include experiments on transmitting signals between the Moon and the Earth.
Quantum teleportation is the transmission of the quantum state of a particle over a distance. For this, a spaced pair of entangled (entangled) particles is used: according to quantum mechanics, even when such particles move away from each other, they retain information about the state of their partner.
