Many worlds interpretation for double slit experiment

TL;DR

This paper critically examines the many worlds interpretation of quantum mechanics in the context of the double slit experiment, questioning its validity and implications for the classical-quantum boundary.

Contribution

It offers a new perspective on quantum superposition and challenges the justification of non-collapsing interpretations like many worlds based on standard quantum theory.

Findings

Questions the validity of the many worlds interpretation.

Suggests no clear boundary between classical and quantum domains.

Highlights issues with the unitary process in isolated systems.

Abstract

As is well known, the double slit experiment contains every key concepts of quantum mechanics such as phase effect, probability wave, quantum interference, quantum superposition. In this article, I will clarify the meaning of quantum superposition in terms of phase effect between states. After applying standard quantum theory, it leads to serious questions about the unitary process of an isolated system. It implies that non collapsing interpretations including many worlds may not be justified. This also could explain that there is no such boundary between classical and quantum domains.
