Description

In this talk, we discuss the quantum entanglement between partons using non-perturbative light-front Hamiltonian methods. By constructing reduced density matrices from hadronic light-front wave functions, we compute von Neumann entropy, mutual information, and linear entropy directly for each parton species. Starting from a simple scalar theory in 3+1D in the strong-coupling regime, we show that the entanglement entropy is directly linked to the Shannon entropy of the transverse momentum dependent parton distributions (TMDs) in the quenched framework. Conversely, the unquenched theory reveals non-classical correlations where entanglement entropy transcends classical parton distribution probabilities. This work establishes entanglement as a fundamental probe of non-perturbative dynamics, providing a roadmap for applications to QCD bound states and future collider phenomenology. Finally, I will also discuss extensions to QCD bound states.
