However, current digital and analog quantum simulation platforms natively provide short-range or power-law couplings that decay too quickly for this purpose. We demonstrate that two spin-$\tfrac12$ chain models -- a staggered nearest-neighbor XXX chain and a long-range XXZ chain -- develop an effective OAT nonlinearity when projected onto the symmetric sector. We show that these dynamics generate metrologically useful spin-squeezed states and Greenberger-Horne-Zeilinger coherences that ensure violation of many-body Bell inequalities. We confirm the accuracy of this mapping by comparing it to the exact dynamics and demonstrate that the generated correlations can be read out using a single probe qubit. The resulting dynamics can be simulated with analog and digital quantum simulators Comments: Subjects: Quantum Physics (quant-ph); Quantum Gases (cond-mat.quant-gas) Cite as: arXiv:2603.17071 [quant-ph] (or arXiv:2603.17071v1 [quant-ph] for this version) https://doi.org/10.48550/arXiv.2603.17071 Focus to learn more arXiv-issued DOI via DataCite (pending registration) Submission history From: Jan Chwedenczuk [view email] [v1] Tue, 17 Mar 2026 19:00:00 UTC (249 KB) Full-text links: Access Paper: View a PDF of the paper titled Generation of many-body Bell correlations with short-range interactions in analog and digital quantum simulators, by Marcin P{\l}odzie\'n and Jan Chwede\'nczukView PDFHTML (experimental)TeX Source view license Current browse context: quant-ph new | recent | 2026-03 Change to browse by: cond-mat cond-mat.quant-gas References & Citations INSPIRE HEP NASA ADSGoogle Scholar Semantic Scholar export BibTeX citation Loading...
