Light from Ancient Quasars Helps Confirm Quantum Entanglement

Quasar

Physicists have provided strong support for quantum entanglement, the seemingly far-out idea that two particles, no matter how distant from each other in space and time, can be inextricably linked, in a way that defies the rules of classical physics.
