In a new study, the ATLAS collaboration successfully observed quantum entanglement at the LHC for the first time. They observed quantum entanglement between top quarks and at the highest energies yet.
To observe entanglement between top quarks, the ATLAS and CMS collaborations studied pairs of top quarks from proton-proton collisions at an energy of 13 teraelectronvolts during the LHC’s second run, from 2015 to 2018.
