On the measurement problem in quantum mechanics: a simple proposal

TL;DR

This paper proposes a new perspective on quantum measurement problems by replacing the wavefunction collapse postulate with the 'Physics Laboratory Assumption', focusing on observables linked to measuring instruments.

Contribution

It introduces the 'Physics Laboratory Assumption' as an alternative framework to address quantum measurement issues, challenging the traditional wavefunction collapse concept.

Findings

Offers a new interpretation of measurement in quantum mechanics.

Provides a conceptual framework avoiding wavefunction collapse.

Addresses well-known quantum paradoxes with the new approach.

Abstract

Some of the problems connected with the interpretation of quantum mechanics are enumerated, in particular those related to some well known paradoxes and, above all, to the measurement process. We then show how the so called "Physics Laboratory Assumption" introduced in [1], which considers as "observables'' only the self-adjoint operators corresponding to existing measuring instruments, can propose a new perspective on the aforementioned problems and can replace the wavefunction collapse postulate.
