That is for instance the case for the 2D toric code, which is demonstrated to be poly-depth twin to 2 decoupled classical Ising spin chains for any system dimension, and we give proof that such dualities maintain for a large class of stabilizer Hamiltonians. Moreover, we prolong the above notion of duality to Lindbladians to be able to present that mixing instances and different portions such because the spectral hole or the modified logarithmic Sobolev inequality are preserved beneath duality.\n    <\/p><\/blockquote><\/div>\n<\/div>\n<div>\n<h2>Submission historical past<\/h2>\n<p> From: Pablo P\u00e1ez-Velasco [view email]                  [v1]<br \/>\n        Thu, 31 Jul 2025 19:25:13 UTC (89 KB)<br \/>\n    [v2]<br \/>\n        Fri, 12 Jun 2026 17:18:11 UTC (190 KB)\n<\/p><\/div>\n<p><br \/>\n<br \/><a href=\"https:\/\/arxiv.org\/abs\/2508.00126\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>[Submitted on 31 Jul 2025 (v1), last revised 12 Jun 2026 (this version, v2)] View a PDF of the paper titled Environment friendly and easy Gibbs state preparation of the 2D toric code through duality to classical Ising chains, by Pablo P&#8217;aez-Velasco and three different authors View PDF Summary:We introduce the notion of polynomial-depth duality [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":1040,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"fifu_image_url":"http:\/\/arxiv.org\/static\/browse\/0.3.4\/images\/arxiv-logo-fb.png","fifu_image_alt":"","jnews-multi-image_gallery":[],"jnews_single_post":[],"jnews_primary_category":[],"jnews_override_bookmark_settings":[],"jnews_social_meta":[],"jnews_override_counter":[],"footnotes":""},"categories":[9],"tags":[1408,1406,362,1405,207,1401,1407,1403,679,1402,1404],"class_list":["post-1038","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-quantum-computing","tag-chains","tag-classical","tag-code","tag-duality","tag-efficient","tag-gibbs","tag-ising","tag-preparation","tag-simple","tag-state","tag-toric"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.7 -
