Experiment opens the door to multi-party quantum communication

(University of Waterloo) In the world of quantum science, Alice and Bob have been talking to one another for years. Charlie joined the conversation a few years ago, but now scientists have measured that their communication occurs faster than the speed of light. Physicists at the Institute for Quantum Computing at the University of Waterloo have demonstrated the distribution of three entangled photons at three different locations, proving quantum nonlocality for more than two entangled photons.
