Schr\"odinger's cat in a realist quantum mechanics

TL;DR

This paper argues that Schr"odinger's cat paradox is resolved within a realist quantum mechanics interpretation by denying the superposition of wave functions representing the same object at different times.

Contribution

It introduces a realist interpretation that eliminates the paradox by rejecting the superposition of wave functions over time.

Findings

Schr"odinger's cat paradox is not valid in a realist interpretation.

Wave functions representing the same object at different times are not superposed.

The interpretation provides a consistent view avoiding the paradox.

Abstract

There is no paradox with Schr\"odinger's cat in a realist interpretation because in such an interpretation wave functions which represent the same object at different times are not to be superposed.
