Abstract

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.

Urbasi Sinha is a Professor at RRI Bangalore, where she heads the Quantum Information and Computing (QuiC) laboratory. She is a Simons Emmy Noether Fellow at the Perimeter Institute, Canada as well as an associate faculty member at IQC, University of Waterloo, Canada, and CQIQC, University of Toronto, Canada. She completed her PhD and M.Sc. in Physics at Cambridge University, UK. She was a Gates Cambridge scholar during her Ph.D. and a Nehru-Chevening scholar during her masters. She was a post-doctoral research associate in the Cavendish labs, Cambridge as well as at IQC Canada. QuIC lab specializes in experiments on photonic quantum information processing including quantum computing and quantum communication, primarily using single and entangled photons and is leading India’s first project on satellite-based secure quantum communications. Her scientific recognitions include the 2017 Homi Bhabha Fellowship, the 2018 ICTP-ICO Gallieno Denardo Award in Optics, being recognised as one of Asia's Top 100 scientists by the Asian Scientist for the year 2019, and the ASSOCHAM Women in Cyber: Making a Difference award in the category “Cyber - Leading from the front” in 2021.
