In these events a Higgs boson briefly splits into a pair of Z bosons, which almost instantly decay into electrons or muons. By reconstructing the emission angles of those measurable particles, the researchers inferred the spins of the original Z bosons and tested whether they were quantum-mechanically linked.<\/p><div id=\"netgu-997048913\" class=\"netgu-content netgu-entity-placement\"><aside class=\"deals-top deals-top--compact\">\n\n\t\t\t<h3 class=\"deals-top__title\">Top-Deals<\/h3>\n\t\n\t\t\t<ul class=\"deals-top__list\">\n\t\t\t\t\t\t\t<li class=\"deals-top__item\">\n\t\t\t\t\t<a class=\"deals-top__link\" href=\"https:\/\/netguide.io\/deals\/de\/deals\/ugreen-aluminium-tabletstaender-360-drehbar-hoehenverstellbar\/\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t<img class=\"deals-top__image\" src=\"https:\/\/netguide.io\/news\/wp-content\/uploads\/sites\/15\/2026\/09\/2825012_1-150x150.webp\" alt=\"\" width=\"52\" height=\"52\" loading=\"lazy\" \/>\n\t\t\t\t\t\t\n\t\t\t\t\t\t<span class=\"deals-top__body\">\n\t\t\t\t\t\t\t<span class=\"deals-top__name\">UGREEN Aluminium Tabletst\u00e4nder | 360\u00b0 Drehbar &amp;

That makes it one of the highest-energy confirmations of entanglement on record. Earlier LHC measurements found the effect in top quarks; seeing it in such heavy, unstable bosons underscores, the team says, how fundamental and robust the effect really is.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Why it matters beyond particle physics<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Entanglement underpins quantum computing and tap-proof communication. Confirming it under the universe&#8217;s most extreme conditions supports the view that quantum mechanics holds even at the highest energies. This is a real experimental measurement, not a simulation or pure theory.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Source: ATLAS collaboration (CERN) and the University of Oxford, published in <a href=\"https:\/\/www.physics.ox.ac.uk\/news\/uncovering-spooky-quantum-effect-large-hadron-collider\" target=\"_blank\" rel=\"noopener\">Physical Review Letters<\/a> on 11 September 2026: \u201cMeasurements of Z-Boson Pair Entanglement in Decays of Higgs Bosons at the ATLAS Experiment,\u201d DOI 10.1103\/y1nh-1b82.<\/em><\/p>\n<div id=\"netgu-3636437532\" class=\"netgu-after-content netgu-entity-placement\"><script async src=\"\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-6258556257245998\" crossorigin=\"anonymous\"><\/script><ins class=\"adsbygoogle\" style=\"display:block;\" data-ad-client=\"ca-pub-6258556257245998\" \ndata-ad-slot=\"4559785002\" \ndata-ad-format=\"auto\"><\/ins>\n<script> \n(adsbygoogle = window.adsbygoogle || []).push({});
