【The Guardian]】Scientists make quantum leap towards a secure new kind of internet 2017-06-16

Scientists have taken a major step towards building a global quantum internet by beaming “entangled” particles of light from a satellite to ground stations more than 700 miles apart.

The feat paves the way for a new kind of internet which draws on the curious ability for subatomic particles to be connected to one another despite being far apart and even on opposite sides of the planet.

Researchers believe that by linking particles together in this way, encrypted information could be sent from place to place across a quantum network with no danger of it being decrypted and read by others, as can be done on the existing internet.
