The Many Hidden Worlds of Quantum Mechanics — Season 1, Episode 8: Quantum Entanglement and Action at a Distance

Episode synopsis

Focus on Einstein's objection to a specific feature of quantum mechanics called entanglement, which he termed, "spooky action at a distance." When two particles are entangled, no matter how far apart they are, if you measure the property of one, you instantly know the corresponding property of the other. Einstein tried to use this feature to argue that quantum mechanics must be incomplete.
