Wigner’s friend paradox: does objective reality not exist?

Abstract

Abstract It is shown that the lack of objective existence of the results of quantum measurements of the state of collapse of the state vector of a remote localized system cannot be proved by an experiment using the reality of violation of Bell’s inequality in the Clauser–Horne–Shimony–Holt form. Arguments of a general nature and a specific calculation example confirming this conclusion are also given.
