The Nobel Prize In Physics 2022
Speaker: Prof. Urbasi Sinha (Raman Research Institute)
The Nobel Prize in Physics for the year 2022 has been awarded jointly to Alain Aspect, John F. Clauser, and Anton Zeilinger “for experiments with entangled photons, establishing the violation of Bell inequalities and pioneering quantum information science’. In this talk, we attempt to discuss the Physics behind the Nobel prize. What
is an entangled state? What are the famous Bell inequalities that John Stewart Bell developed? What does violation of Bell inequalities entail? And what did John F. Clauser, Alain Aspect, and Anton Zeilinger do towards experiments on entangled photons and Bell inequalities? These are some of the questions we attempt to find answers to during this talk. We end the talk by discussing some of the revolutionary new technologies that are a direct consequence of the Nobel prize-winning work.
