Prof. Dr. Anton Ramšak, Assoc. Prof. Dr. Rainer Kaltenbaek (FMF): Quantum entanglement and the Nobel Prize in Physics 2022

In their 1935 article, Einstein, Podolsky and Rosen questioned whether the description of reality within the framework of quantum mechanics and wave functions is truly complete. Today, quantum entanglement, which gave rise to doubts at that time, is widely accepted as one of the fundamental properties of quantum mechanics. Moreover, quantum entanglement has proved an essential resource for a multitude of applications in quantum communication, quantum sensing, and quantum computing.
John Clauser, Alain Aspect, and Anton Zeilinger have each conducted groundbreaking experiments with entangled quantum states, in which multiple particles behave as one even when they are separated. Their work was awarded the 2022 Nobel Prize in Physics, and their results have proven the reliability of quantum mechanics and paved the way for new technologies based on quantum information.
We will present the nearly century-long history of theoretical and experimental efforts to discover and test the phenomenon of quantum entanglement.
