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.

On "Einstein's Quantum Riddle," 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.
