Quantum Measurement Without Collapse

TL;DR

This paper proposes a quantum measurement interpretation that avoids wave function collapse by emphasizing the compatibility of observables, offering a self-consistent view and resolving the Schrödinger Cat paradox.

Contribution

It introduces a novel interpretation of quantum measurement that eliminates collapse by focusing on compatible observables and provides a consistent framework.

Findings

Avoids wave function collapse in quantum measurement

Provides a self-consistent interpretation of measurement

Offers a solution to the Schrödinger Cat paradox

Abstract

It is shown that the classical book by von Neumann proposing dynamics of measured systems with "reduction (or collapse) of system's wave packet" contains also hints how to avoid this discontinuity in time evolution of the measured system (hence it is in this point not quite selfconsistent). The possibility of avoiding that collapse is a consequence of the observation that any "human observer" can observe simultaneously just mutually compatible "observables". In the paper it is shown how to describe this fact and its consequences. The proposed interpretation of quantum measurement leads also to trivial solution of the "Schr\"odinger Cat Paradox".
