CERN's ATLAS Experiment Observes Quantum Entanglement in Higgs Boson Decays

The ATLAS experiment at CERN's Large Hadron Collider has provided strong evidence of quantum entanglement between Z bosons resulting from Higgs boson decays. This significant discovery extends the observation of quantum entanglement into extremely high-energy environments, demonstrating its presence between massive, short-lived particles produced in proton collisions. The findings, published in Physical Review Letters, advance our understanding of fundamental physics.
