  The phenomenon of jet quenching, related to the momentum broadening of a
high-energy parton, provides important experimental evidence for the production
of a strongly coupled, deconfined medium in heavy-ion collisions. Its
theoretical description has been addressed in a number of works, both
perturbatively and non-perturbatively (using the gauge-gravity duality). In
this contribution, following a proposal by Caron-Huot, we discuss a novel
approach to this problem, enabling one to extract non-perturbative information
on this real-time phenomenon from simulations on a Euclidean lattice.
