  We study the generation of superpositions of N00N states by overlapping
few-photon-subtracted squeezed vacuum states and coherent states on a 50/50
beam splitter. Assuming parameters that are feasible with current technology
results in output states with mean photon numbers of several tens. We show that
the generated quantum states violate local realism even in the presence of
considerable loss. The occurrence of strong quantum correlations for mesoscopic
quantum states of light is particularly beneficial for coupling light and
matter quantum systems.
