The realization of the wave function collapse in the linguistic interpretation of quantum mechanics

TL;DR

This paper demonstrates how wave function collapse phenomena can be realized within the linguistic interpretation of quantum mechanics, challenging traditional views and justifying the von Neumann-Lüders projection postulate.

Contribution

It introduces a way to realize wave function collapse in the linguistic interpretation, providing a new perspective on quantum measurement without actual collapse.

Findings

Wave function collapse can be modeled in the linguistic interpretation.

Justification of the von Neumann-Lüders projection postulate is proposed.

Wave function collapse should not be adopted in the Copenhagen interpretation.

Abstract

Recently I proposed the linguistic interpretation of quantum mechanics, which is characterized as the linguistic turn of the Copenhagen interpretation of quantum mechanics. This turn from physics to language does not only extend quantum theory to classical theory but also yield the quantum mechanical world view. Although the wave function collapse is prohibited in the linguistic interpretation, in this paper I show that the phenomenon like wave function collapse can be realized in the linguistic interpretation. And furthermore, I propose the justification of the von Neumann-L\"uders projection postulate. After all, I conclude that the wave function collapse should not be adopted in the Copenhagen interpretation.
