Is a nondemolition measurement of the quantum state vector collapse of a remote localised system possible?

Faculty of Physics, Lomonosov Moscow State University
By the example of an experiment that implements, according to its authors, Wigner friends' paradox, the impossibility of measuring the state vector collapse of a remote localised system is shown. It is also found that the objectivity of the results of quantum measurements is not violated in this case.
