Abstract: There exists some misunderstanding that the 2022 Nobel Prize in physics was awarded for proving quantum entanglement. As a matter of fact, even Einstein himself admitted the quantum entanglement phenomenon; the problem is how to explain it. The value of this year's Nobel Prize in physics lies in the unambiguous experimental demonstration that the Bell's inequality expression based on local hidden variables is invalid. Many articles have been published on this event, but they lack a detailed derivation of the quantum mechanical contradiction to Bell's inequality. In addition, most, if not all, articles emphasize only the academic significance of quantum entanglement, with almost no comment on its philosophical meaning or criticism on the abuse of the concept of quantum entanglement. This paper intends to provide a supplement for these two aspects.
