The locality of quantum subsystems II: A 'local sum-over-paths' ontology for quantum subsystems

TL;DR

This paper introduces a local hidden variable theory for quantum subsystems using a modified sum-over-paths approach, addressing the non-locality issue in entangled quantum systems.

Contribution

It presents a novel local interpretation of quantum subsystems based on a modified sum-over-paths framework, dissociating wavefunction structure from information flow.

Findings

Constructs a local hidden variable model for quantum subsystems

Demonstrates how information flow can be localized during interactions

Provides a new perspective on quantum non-locality and entanglement

Abstract

Subsystems of entangled quantum systems are not traditionally described in a local way. This paper begins to address the issue by constructing an explicit local hidden variable theory for quantum subsystems. The interpretation is based on a modified sum-over-paths approach, where the paths of the subsystem obtain information about the external system during interactions. The interpretation utilizes the conception that there is a dissociation between the tensor product structure of wavefunctions and information flow into quantum subsystems.
