Abstract: Some macroscopic models for diffusive quantum systems are reviewed. The model equations are derived from Wigner-Boltzmann equations by a moment method. Depending on the properties of the collision operator and the scaling of the Wigner equation, three model classes are presented: the quantum drift-diffusion equations, inviscid and viscous quantum hydrodynamic equations, and quantum Navier-Stokes equations. For each of these models, the derivation is sketched and analytical results are reviewed.
