Description
Quark jets are powerful probes of the matter created in ultrarelativistic heavy-ion collisions, from the dense gluon fields of the initial-stage Glasma to the hot quark-gluon plasma. In this talk, I present our recent progress on developing a non-perturbative computational framework for in-medium jet evolution based on the light-front QCD Hamiltonian approach. By treating the jet as a fully quantum state rather than a classical probe, our method enables a real-time description of jet propagation through color background fields. I first show results for jet momentum broadening in the Glasma, where we compute the jet quenching parameter at mid-rapidity and reveal anisotropies between the longitudinal and transverse directions with respect to the collision axis. I then discuss how this framework has been extended to digital quantum simulations, allowing us to track multi-particle jet evolution in stochastic color background fields and extract medium-induced observables such as momentum broadening and gluon production. Together, these studies establish a systematic, non-perturbative approach to real-time jet dynamics and lay the groundwork for future quantum simulation of QCD jet physics.
