Light from Ancient Quasars Helps Confirm Quantum Mechanics of Entanglement
CAMBRIDGE, Mass., Aug. 23, 2018 — An international research team has extended the case for quantum entanglement, further limiting the possibility that a freedom-of-choice loophole might reveal that such correlations could have a classical explanation. The team, comprising researchers from MIT, the Austrian Academy of Sciences, and the University of Vienna, as well as physicists from Harvey Mudd College and the University of California, San Diego, used distant quasars to determine the measurements to be made on pairs of
