Nova Einsteins Quantum Riddle

Join scientists as they grab light from across the universe to prove quantum entanglement is real. Einstein called it spooky action at a distance, but today quantum entanglement is poised to revolutionize technology from computers to cryptography. Physicists have gradually become convinced that the phenomenon two subatomic particles that mirror changes in each other instantaneously over any distance is real. But a few doubts remain. NOVA follows a ground-breaking experiment in the Canary Islands to use quasars at opposite ends of the universe to once and for all settle remaining questions.
