European scientists propose world’s largest quantum network, between Earth and the ISS
Meanwhile, in the USA we are trying to convince Americans global warming is real and man made and keep voodoo creationism out of the classroom and that the world is not run by shape changing alien lizards out to take our guns and turn our children gay as our scientific agenda.

European scientists propose world’s largest quantum network, between Earth and the ISS

A group of European researchers has proposed the largest quantum network yet: Between Earth and the International Space Station. Such a network would see entangled photons transmitted over a distance of 250 miles — two or three times greater than previous quantum communication experiments. Not only will this be the first quantum experiment in space, but it will allow the scientists to see if entanglement really is instantaneous over long distances, and whether it’s affected by gravity.
In recent years, quantum physicists have successfully teleported entangled photons over a free-space distance of 143 kilometers (89 miles) using lasers, and 250 kilometers (155 miles) over optical fiber in the lab. In the past year we have also seen the first ground-to-air network, between a base station and an airplane flying 20 kilometers (12 miles) above. These were impressive feats, but to prove the possibility of a worldwide, satellite-based quantum network, larger distances are needed — something like the 400 kilometers (248 miles) to the ISS. —->Continued
