Intrinsic properties of quantum systems

TL;DR

This paper introduces a realist interpretation of quantum mechanics distinguishing intrinsic and extrinsic properties, offering a new framework for understanding classical states, quantum cosmology, and the measurement problem.

Contribution

It proposes a novel classification of quantum properties into intrinsic and extrinsic, providing a systematic interpretation that extends beyond Copenhagen.

Findings

Intrinsic properties can be attributed without violating quantum mechanics

A new quantum definition of classical states is proposed

The approach offers insights into quantum cosmology and measurement

Abstract

A new realist interpretation of quantum mechanics is introduced. Quantum systems are shown to have two kinds of properties: the usual ones described by values of quantum observables, which are called extrinsic, and those that can be attributed to individual quantum systems without violating standard quantum mechanics, which are called intrinsic. The intrinsic properties are classified into structural and conditional. A systematic and self-consistent account is given. Much more statements become meaningful than any version of Copenhagen interpretation would allow. A new approach to classical properties, quantum cosmology and measurement problem is suggested. A quantum definition of classical states is proposed.
