A model of quantum decoherence from string breaking explains hyperon spin correlations by linking vacuum entanglement to observed data in non-perturbative QCD.
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.
Hyperon spin correlations in high-energy collisions are consistent with a two-qubit depolarizing channel, from which a Lindblad master equation is derived for hadronization spin dynamics.
Scalar Lambda-pair spin correlations leave a continuous density-matrix degeneracy; full tensor tomography is required to claim entanglement, and a ³P₀ benchmark predicts a specific anisotropy pattern.
A quantum simulation framework is developed and demonstrated for energy loss and hadronization of a heavy quark in 1+1D SU(2) lattice gauge theory on 18 qubits of IBM hardware, with results matching classical simulations.
Phenomenological calculation of entanglement entropies in B0 → VV decays shows strong dependence on relative phases and a correlation with branching fractions that the authors link to weak and strong interaction dynamics.
A review summarizing advancements in probing quantum entanglement and Bell inequalities using high-energy particle colliders.
