On the Relative Nature of Quantum Individuals

TL;DR

This paper challenges the traditional atomist view of quantum mechanics, proposing a new, relation-based concept of quantum individuals that is relative yet invariant across different representations.

Contribution

It introduces a novel understanding of quantum individuals as relation-based entities, opposing the standard particle-centric interpretation of quantum theory.

Findings

Quantum individuality is defined by relations within a specific complexity level.

Quantum individuals are relative concepts dependent on bases and factorizations.

The proposed framework maintains invariance despite relational relativity.

Abstract

In this work we argue against the interpretation that underlies the "Standard" account of Quantum Mechanics (SQM) that was established during the 1930s by Niels Bohr and Paul Dirac. Ever since, following this orthodox narrative, physicists have dogmatically proclaimed -- quite regardless of the deep contradictions and problems -- that the the theory of quanta describes a microscopic realm composed of elementary particles (such as electrons, protons and neutrons) which underly our macroscopic world composed of tables, chairs and dogs. After critically addressing this atomist dogma still present today in contemporary (quantum) physics and philosophy, we present a new understanding of quantum individuals defined as the minimum set of relations within a specific degree of complexity capable to account for all relations within that same degree. In this case, quantum individuality is not conceived in absolute terms but -- instead -- as an objectively relative concept which even though depends of the choice of bases and factorizations remain nonetheless part of the same invariant representation.
