We experimentally perform the simulation of open quantum dynamics in single-qudit
systems. Using a spatial light modulator as a dissipative optical device, we
implement dissipative-dynamical maps onto qudits encoded in the transverse
momentum of spontaneous parametric down-converted photon pairs. We show a
well-controlled technique to prepare entangled qudits states as well as to
implement dissipative local measurements; the latter realize two specific
dynamics: dephasing and amplitude damping. Our work represents a new
analogy-dynamical experiment for simulating an open quantum system.
