On page 64 of the January 2014 issue of BBC Focus magazine, it mentions about the Japanese Space Agency's SOCRATES satellite (Space Optical Communications Research Advanced Technology Satellite) that will "distribute entangled pairs of particles to act as quantum keys, the precursor of a worldwide entanglement network".
Does anyone have more information about this?
How long do you think it will be before this "worldwide entanglement network" becomes as accessible as the World Wide Web?
