N2 - We have performed experimental quantum state tomography of NOON states with up to four photons. The measured states are generated by mixing photons from a classical coherent state with down-converted photon pairs. We show that the fidelity between the produced states and the ideal NOON states is high. The fidelity is limited by the overlap of the two-photon down-converted state with any two photons originating from the coherent state, for which we introduce and measure a figure of merit. A second limitation on the fidelity set by the total setup transmission is discussed. We also apply the same tomography procedure for characterizing correlated photon hole states.
