TOPIC:Physics Strong evidence for quantum entanglement between Z bosons found by ATLAS and CMS The mind-bending phenomenon is now becoming evident in a new particle Written by: Rory Harris — 17 September, 2026 Artistic impression of quantum entanglement between two Z bosons (Image: Daniel Dominguez/CERN) Quantum entanglement is certainly one of the stranger concepts to have emerged from the melting pot of 20th-century physics. Many great physicists, including Einstein, struggled to accept that the phenomenon could be real but, for decades now, the number of examples demonstrating it has been increasing. And, recently, the ATLAS and CMS Collaborations have added to these results by finding st...
