Nova: Einstein's Quantum Riddle - Nova: Einstein's Quantum Riddle - DVD

Einstein called it "spooky action at a distance," but today quantum entanglement is poised to revolutionize technology. Physicists have become gradually convinced that quantum entanglement 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.
