Impossible: Physics beyond the Edge

Entanglement and Quantum Cloning (1x21)

Air date: Jan 01, 2010

Delve into the weirdest of all quantum phenomena: entanglement, which causes a pair of quantum particles to behave as if they are telepathically connected. By cloning quantum particles, this effect could, in theory, allow faster-than-light signals, but there are fundamental reasons this is impossible.
