The Nobel Prize in Physics 2022: Quantum Entanglement and Bell's Experiments

Explore a comprehensive lecture on the groundbreaking research that led to the 2022 Nobel Prize in Physics, delivered by Prof. Urbasi Sinha at WOPI 2022. Delve into fundamental quantum physics concepts including entanglement, locality, and realism through accessible explanations like the cat analogy. Learn about pivotal experiments, their assumptions, and technical challenges, including Bell's strong locality condition and acoustoptic modulation. Discover cutting-edge applications in quantum technology such as teleportation, satellite-based quantum communications, quantum key distribution, and random number generation. Understand the significance of loophole-free experiments and their role in advancing quantum communications. Examine the future of quantum technology through discussions of quantum repeaters, entanglement swapping, and the ongoing quest to increase communication distances in satellite-based systems.
