Einstein’s ‘spooky action’ survives one of the most extreme tests yet: CERN finds heavy Z bosons can become quantum-entangled

Physicists at CERN’s Large Hadron Collider have found strong evidence for quantum entanglement. Two short-lived Z bosons, produced from a Higgs boson decay, showed quantum correlations. This observation confirms quantum mechanics’ strange predictions in extreme energy environments. Researchers reconstructed Z boson properties from their decay products for analysis. Future experiments will further investigate quantum phenomena at even higher energies.
