CERN confirms quantum entanglement survives high-energy collisions

Physicists at CERN’s Large Hadron Collider (LHC) have confirmed that quantum entanglement can survive extreme, high-energy particle collisions. Using the ATLAS detector, researchers observed entanglement between pairs of Z bosons produced during the decay of Higgs bosons.

Because Z bosons exist only momentarily, the team reconstructed their properties by analyzing the electrons and muons left in their wake. This discovery marks one of the highest-energy confirmations of entanglement ever recorded. Unlike previous observations involving top quarks, Z bosons possess three spin states, known as qutrits, which adds a new layer of complexity to the study of quantum mechanics in high-energy environments.

In addition to the entanglement findings, researchers reported the identification of a rare new baryon, the Xi-cc-plus, during recent accelerator runs.
