- Abstract: QCD jets provide one of the best avenues to extract information about the
quark-gluon plasma produced in the aftermath of ultra relativistic heavy ions
collisions. The structure of jets is determined by multiparticle quantum
interference hard to tackle using perturbative methods. When jets evolve in a
QCD medium this interference pattern is modified, adding another layer of
complexity. By taking advantage of the recent developments in quantum
technologies, such effects might be better understood via direct quantum
simulation of jet evolution. In this work, we introduce a precursor to such
simulations. Based on the light-front Hamiltonian formalism, we construct a
digital quantum circuit that tracks the evolution of a single hard probe in the
presence of a stochastic color background. In terms of the jet quenching
parameter $\hat q$, the results obtained using classical simulators of ideal
quantum computers agree with known analytical results. With this study, we hope
to provide a baseline for future in-medium jet physics studies using quantum
computers.
