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 with spacelike separation, scientists have measured that their communication occurs faster than the speed of light. For the first time, physicists have demonstrated the distribution of three entangled photons at three different locations (Alice, Bob and Charlie) several hundreds of meters apart, proving quantum nonlocality for more than two entangled photons.
