Quantum Entanglement Verified in Z Bosons at CERN's Large Hadron Collider

Physicists from the University of Oxford, collaborating with CERN's ATLAS experiment, have confirmed quantum entanglement among Z bosons produced from Higgs boson decays at the Large Hadron Collider. This discovery, published in Physical Review Letters, demonstrates the robustness of quantum entanglement in high-energy collisions involving heavy, short-lived particles, marking one of the highest-energy confirmations to date.
