Testing “spooky action-at-a-distance” on the International Space Station
June 9th, 2008 | by KFC |



Entanglement is the strange and beautiful property of certain quantum particles to become so deeply linked that they share the same existence. According to quantum theory, that link should be maintained whatever the distance between the particles, whether the width of an atom or the diameter of the universe.

This led Einstein to claim that the instantaneous effects of entanglement would lead to “spooky action-at-a-distance” in violation of special relativity which prevents faster-than-light signals.

Nobody knows how the different predictions of relativity and quantum mechanics can be resolved. However, entanglement has been measured in numerous experiments over relatively short distances on Earth. The tests involve two entangled particles, photons say, being sent to distant experimenters who then perform measurements on them.
