Quantum simulation of jet quenching in nuclear environments

Jet quenching has been used as a probe of the quark-gluon plasma in heavy ion collisions for decades. Traditional approaches of understanding parton in-medium dynamics are based on a perturbative description of parton splitting with medium modifications and have difficulties in analyzing a quantum interference effect called the Landau-Pomeranchuk-Migdal (LPM) effect, for processes with more than two splittings. In this talk, I will show a framework for quantum simulation of jet in-medium evolution. The framework is based on the light-front Hamiltonian dynamics of QCD which contains a kinetic evolution term, transverse momentum exchange between partons and the medium and parton splitting/recombination. I will argue that very likely we can efficiently simulate the jet in-medium evolution on a quantum computer. The framework automatically keeps track of quantum interference and thus can be applied to study the LPM effect with more than two splittings, no matter whether the medium is static or expanding, thin or thick, hot or cold. Some quantum simulation results of a toy model will also be presented, where the LPM effect that suppresses the radiation probability is observed.
