Quantum Entanglement Endures Higgs Decays at the LHC
Physicists from CERN's ATLAS collaboration have observed strong evidence that quantum entanglement survives the LHC's extreme energies. By studying Higgs boson decays into pairs of Z bosons (which quickly decay into electrons or muons) at 13 TeV, they infer the Z bosons' spins and confirm entanglement in high-energy collider events. This marks one of the highest-energy confirmations of entanglement and extends foundational quantum mechanics tests into violent, laboratory-scale particle collisions; the results are published in Physical Review Letters.
