Simulation of interacting electron systems is one of the great challenges ofmodern quantum chemistry and solid state physics. Controllable quantum systemsoffer the opportunity to create artificial structures which mimic the system ofinterest. An interesting quantity to extract from these quantum simulations isthe spectral function. We map a noisy quantum simulator onto a fermionic systemand investigate the influence of decoherence on the simulation of the spectraldensity using a diagrammatic approach on Keldysh contour. We show that featuresstronger than the single-qubit decoherence rate can be resolved, while weakerfeatures wash out. For small systems, we compare our Keldysh approach tomaster-equation calculations.
