ON INDIVIDUALITY IN QUANTUM THEORY

Abstract

A quantum mechanical analysis of the decomposability of quantum systems into subsystems provides support for the so-called "attenuated Eliminative Ontic Structural Realism" within Categorical Structuralism studies in physics. Quantum subsystems are recognized as non-individual, relationally defined objects that deflate or relax some standard objections against Eliminative Ontic Structural Realism. Our considerations assume the universally valid quantum theory without tackling interpretational issues.

O INDIVIDUALNOSTI U KVANTNOJ TEORIJI

Kvantnomehanička analiza dekompozabilnosti kvantnih sistema u podsisteme pruža podršku za takozvanu eliminativnu ontičku strukturalnu realnost, „attenuated Eliminative Ontic Structural Realism” (EOSR), u okvirima kategoričkih studija u fizici. Kvantni podsistemi se pojavljuju kao neindividualni, relacioni objekti, što umanjuje neke od postojećih primedaba na EOSR. Naša razmatranja podrazumevaju univerzalno važeću kvantnu teoriju bez dodira sa interpretacijskim pitanjima.

HIGHLIGHTS

• Quantum theory does not offer a unique ground for the familiar classical individuality.
• The emerging field of the so-called quantum structural studies offers new insights and tools for addressing this issue.
• The approach originally developed by Jasmina Jeknić-Dugić et al. points out the new avenues in this regard.
• A qualitative agreement with the so-called Eliminative Ontic Structural Realism is recognized and discussed.
