A portable system that will allow electronic messages to be transmitted to and from satellites in absolute secrecy has now been built by researchers at Los Alamos National Laboratory in New Mexico. The researchers will test the system to send quantum information 10 kilometres through horizontal free space at the start of September. Air density at this at this level approaches that experienced when transmitting information to a satellite 300 kilometres above the Earth.
