3 physicists share Nobel for work on quantum science

Frenchman Alain Aspect, American John F Clauser and Austrian Anton Zeilinger were cited by the Royal Swedish Academy of Sciences for discovering the way that unseen particles, such as photons, can be linked or “entangled”, with each other even when they are separated by large distances, a field that unsettled Albert Einstein himself, who once referred to it in a letter as “spooky action at a distance”.
