    "abstract": "Using a Hong-Ou-Mandel interferometer, we apply the techniques of quantum\nprocess tomography to characterize errors and decoherence in a prototypical\ntwo-photon operation, a singlet-state filter. The quantum process tomography\nresults indicate a large asymmetry in the process and also the required\noperation to correct for this asymmetry. Finally, we quantify errors and\ndecoherence of the filtering operation after this modification.",
