Observation of quantum entanglement with top quarks at the ATLAS detector - Nature
Briefly

The Large Hadron Collider (LHC) has demonstrated potential in studying quantum mechanics by examining the spin correlation between the top quark and its antiquark, uncovering quantum entanglement.
Entangled particles exhibit correlations that defy simple independent descriptions, a critical aspect explored through the top quark pairs in high-energy proton-proton collisions at the LHC.
