China has carried out quantum teleportation on distance 1,2 thousand kilometers
it is published in the Science magazine, briefly reports Scientific and technical university of China about it.
During the experiments violation of inequalities Bella has been shown (and, as a result, the principle of locality). Efficiency of information transfer by a new method on 17 orders exceeds indicators of widespread commercial fiber-optic cables.
Quantum teleportation was carried out by means of pair of satellites and three earth-based stations between which distance varies within 500-2000 kilometers. Between two of such earth-based stations the distance has made record 1,2 thousand kilometers.
Quantum teleportation represents transfer of a quantum condition of a particle on distance. The carried couple of linked (tangled) particles is for this purpose used: according to quantum mechanics, even during removal of such particles from each other they save information on a condition of the partner (the principle of local realism is carried out).
what is the implication for future ?
