A step toward practical quantum encryption over free-space networks

[frogboy]

Researchers have sent a quantum-secured message containing more than one bit of information per photon through the air above a city. The demonstration showed that it could one day be practical to use high-capacity, free-space quantum communication to create a highly secure link between ground-based networks and satellites, a requirement for creating a global quantum encryption network.

Would love to try it myself, but unfortunately my flux capacitor is undergoing inspection at the moment.

All jokes aside, this is really phenomenal. It's amazing how far we've come while just barely scratching the surface. The future might prove quite interesting.
Some Austrian university has been testing communication via quantum entanglement, imagine that combined with high-dimensional, multibit messages. Crazy.
