According to general relativity, it is, as physical quantities (perceptible or not) in two spacelike separated regions cannot affect one another. Yet, in quantum theory, it has traditionally been thought that local realism cannot hold and that such effects do occur. This apparent discrepancy between the two theories is resolved by Everettian quantum theory, as first proven by Deutsch & Hayden (2000). In this paper, I will explain how local realism is respected in quantum theory and review the advances in our understanding of locality since Deutsch & Hayden's work, including the concept of local branching and the more general analysis by Raymond-Robichaud (2021) Subjects: Quantum Physics (quant-ph) Cite as: arXiv:2601.06522 [quant-ph] (or arXiv:2601.06522v1 [quant-ph] for this version) https://doi.org/10.48550/arXiv.2601.06522 Focus to learn more arXiv-issued DOI via DataCite (pending registration) Submission history From: Samuel Kuypers [view email] [v1] Sat, 10 Jan 2026 10:46:51 UTC (27 KB) Full-text links: Access Paper: View a PDF of the paper titled Restoring Locality: The Heisenberg Picture as a Separable Description of Quantum Theory, by Sam KuypersView PDFHTML (experimental)TeX Source view license Current browse context: quant-ph new | recent | 2026-01 References & Citations INSPIRE HEP NASA ADSGoogle Scholar Semantic Scholar export BibTeX citation Loading...
