3 physicists share Nobel Prize for work on quantum science

Three scientists jointly won this year’s Nobel Prize in physics Tuesday for proving that tiny particles could retain a connection with each other even when separated, a phenomenon once doubted but now being explored for potential real-world applications such as encrypting information. Frenchman Alain Aspect, American John F. Clauser and Austrian Anton Zeilinger were cited by the Royal Swedish Academy of Sciences for experiments proving the “totally crazy” field of quantum entanglements to be all too real. I’m doing this purely out of curiosity.’” In quantum entanglement, establishing common information between two photons not near each other “allows us to do things like secret communication, in ways which weren’t possible to do before,” said David Haviland, chair of the Nobel Committee for Physics. Quantum information “has broad and potential implications in areas such as secure information transfer, quantum computing and sensing technology,” said Eva Olsson, a member of the Nobel committee. “Its predictions have opened doors to another world, and it has also shaken the very foundations of how we interpret measurements.” The kind of secure communication used by China’s Micius satellite — as well as by some banks — is a “success story of quantum entanglement,” said Harun Siljak of Trinity College Dublin.
