CERN Finds Entanglement in Higgs-Born Z Bosons, Challenging Virtual Particle Concepts
Physicists at CERN’s Large Hadron Collider have detected strong evidence of quantum entanglement between pairs of Z bosons produced by the decay of a Higgs boson. This marks the first time entanglement has been observed in elementary particles acting as qutrits, distinct from the two-state qubits of top quarks. The finding, published in Physical Review Letters, suggests that even 'virtual' particles, which cannot be directly observed, may possess genuine quantum properties like spin entanglement. Although the statistical significance reached 4.7 sigma, just short of the 5-sigma discovery threshold, the data provides compelling evidence for this phenomenon.
