They are Alain Aspect, John F. Clauser and Anton Zeilinger “for experiments with entangled photons, establishing the violation of Bell inequalities and pioneering quantum information science”.
The Norwegian Nobel Committee has awarded Nobel Prize in Physics 2022 to three laureates from the USA, France, and Austria for their contributions to the field of quantum mechanics. They are Alain Aspect, John F. Clauser and Anton Zeilinger “for experiments with entangled photons, establishing the violation of Bell inequalities and pioneering quantum information science”.
The ground-breaking experiments in the field of quantum entanglement are to investigate and control particles that are in an entangled state. Their experiment determines the behaviour of the particles in an entangled form even though they are separated by a large distance. The experimental tools developed by the three laureates have laid the groundwork for a new era of quantum physics.
Quantum mechanics
Quantum mechanics is a fundamental part of Physics that describes the physical properties of nature in the forms of atoms and subatomic particles. It is the foundation of quantum information science.
Bell inequalities
In the words of physicist John Stewart Bell, Bell inequalities was named. The Bell inequalities show that local hidden-variable theories and quantum mechanics cannot coexist. Existing values are incompatible with what quantum theory predicts.
