Toponium strengthens the spin-singlet component in top-quark pairs, substantially enhancing entanglement and enabling observable quantum steering at 10 sigma and Bell nonlocality at 9 sigma near threshold with current LHC data.
NLO QCD corrections enhance the γγ → ttbar cross section while leaving spin observables largely unchanged, with entanglement peaking near threshold and both entanglement and Bell nonlocality depending strongly on beam polarization.
