Description
Hadronization, the dynamical realization of color confinement in QCD, is the central process connecting the quark-gluon plasma (QGP) produced in relativistic heavy-ion collisions to the hadronic observables measured in detectors. Yet it remains beyond the reach of existing first-principles frameworks, as semi-classical generators lose quantum coherence while lattice QCD cannot access real-time Minkowskian dynamics. Quantum computing offers a natural solution: the ability to track unitary evolution of entangled many-body states makes it ideally suited to the real-time, non-perturbative dynamics.
In this talk I present two complementary quantum simulation approaches to hadronization and related processes in heavy-ion collisions. In the light-front framework, I discuss real-time jet evolution in QGP media, including momentum broadening, gluon production, entropy growth, and color decoherence in dijet systems, alongside the preparation of hadronic bound states via variational quantum algorithms. In the equal-time lattice framework, I discuss real-time string breaking, hadronic scattering, and non-equilibrium dynamics in lower-dimensional gauge theories, where quantum information science tools such as tensor networks provide powerful and efficient classical benchmarks. Both approaches carry unique strengths, and together they build toward a first-principles quantum simulation framework for the full hadronization process, connecting real-time parton dynamics to non-perturbative hadronic structure.
