‘Perfect entanglement’ of two light beams has opened a major step towards highly secure quantum communication systems.
The University of Queensland’s Professor Tim Ralph and his colleagues from Canada and Russia have developed a technique to restore entangled light beams that have been distributed between distant points.

Albert Einstein famously dismissed quantum physics as “spooky action at a distance”, but quantum science may have the last word, with researchers in Brisbane and Tokyo finally providing the missing experimental proof.
