Commentary on the 2022 the Nobel Prize in Physics

This year’s Nobel Prize in physics was awarded to Alain Aspect, John Clauser and Anton Zeilinger. They are the scientists who completed the excellent experimental work on the verification of entanglement through the violation of Bell’s inequality. In my opinion, the announcement can be viewed as surprising news on the one hand while it also can be taken for granted on the other hand. It is because the field of the foundations of physics is conventionally considered to be lacking in its applicabilities, but the impact of this year’s Nobel Prize winning discovery is very far-reaching. Here, in this article, I provide a detailed explanation of the Nobel Prize winning topic and make a couple of comments on the experiments.
