First quantum encrypted network goes live

The first network protected by quantum encryption has gone live at a scientific conference in Vienna...

The quantum cryptography systems rely on an application of the Heisenberg Uncertainty Principle, which broadly states that it is impossible to observe quantum information without altering it.

This makes eavesdropping impossible, since as soon as it takes place the change in data can be recognised and the network shut down. (more)
