Prof. Arvind teaches physics and is a Former Vice Chancellor (Punjabi University Patiala). In this talk delivered at Azim Premji University, Bengaluru Campus -- he will talk about the "First Quantum Revolution", which took place at the beginning of the 20th century. This period saw the birth of quantum mechanics and a paradigm shift from classical to quantum physics. The basic departure in our thinking about the world that quantum mechanics has brought about will be described. The counterintuitive aspects of the quantum framework used to describe physical reality will be elaborated upon. The key quantum notions of superposition, measurement and entanglement will be described.
The criticism of Einstein via his EPR paper, developments related to Bell's inequalities, observations of Bell violations in experiments, and finally, the Physics Nobel Prizes of 2022 will be discussed.
The talk will also briefly touch upon the "Second Quantum Revolution" which encompassed the applications of quantum theory to develop pathbreaking technologies ranging from computers to semiconducting devices to lasers and superconductors. The talk will end with a discussion about the "Third Quantum Revolution", which took place towards the end of the 20th century and brought together key ideas from quantum physics and classical information theory. The new developments that are currently taking place in the areas of quantum communication, quantum metrology, and quantum computing will be discussed.
