Today the Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics 2022 to Alain Aspect, John Clauser and Anton Zeilinger, for experiments with entangled photons, establishing the violation of Bell inequalities and pioneering quantum information science. This is an enormous recognition of the field of quantum information science, in which QuTech finds its roots.
The Royal Swedish Academy of Sciences explains: “Alain Aspect, John Clauser and Anton Zeilinger have each conducted groundbreaking experiments using entangled quantum states, where two particles behave like a single unit even when they are separated. Their results have cleared the way for new technology based upon quantum information.”
Loophole-free Bell inequality violation at QuTech
Current developments build further on the pioneering work of the Nobel laureates 30–50 years later. They are recognised as the generation that has led the way. For example, in 2015 Ronald Hanson has demonstrated the first Bell inequality violation over a distance of 1.3 kilometers.
