Analysis of ~10 billion muon decays from Fermilab g-2 data shows 5.5σ Leggett-Garg inequality violation via reconstructed temporal polarization correlators.
A modular two-qubit quantum circuit primitive is built to reproduce QCD gluon-splitting entanglement via concurrence, with parameters fitted to LHC data and validated on hardware for three-prong jets.
An automated framework in MadGraph5_aMC@NLO computes tree-level production spin-density matrices and quantum observables for generic collider processes, with validation on ttbar and VV and new applications to multi-top final states.
Quantum information observables in LHC top quark pair production are modified by SMEFT dimension-6 operators in ways that depend on their CP properties, offering a complementary probe beyond standard observables.
Transverse polarization in e+e- collisions generates maximally entangled fermion pairs in QED processes and boosts entanglement in electroweak and Bhabha scattering.
Simulations of pp to tau+ tau- at the LHC with ML neutrino reconstruction show Bell nonlocality above 5 sigma, proposing tau pairs as a new benchmark system for quantum information studies.
SVD-based numerical method reconstructs the two-fold ambiguous tau momenta in pi nu decays and shows entanglement observables remain extractable despite unresolved solutions.
