Sci/Tech: Scientists demonstrate quantum nature of entanglement swapping

Scientists demonstrate quantum nature of entanglement swapping from PhysOrg.com

As if plain old quantum entanglement weren’t strange enough for modern physics, now physicists are entangling already entangled particles. In entanglement swapping, one particle of an entangled pair becomes entangled with a third particle, which itself becomes entangled with the other particle in the first pair, even though the two never interact. Here’s how physicists are unraveling this behavior and manipulating it for use in quantum communications and high-speed computing.
