RT Journal Article T1 Complete characterization of arbitrary quantum measurement processes A1 Luis Aina, Alfredo A1 Sánchez Soto, Luis Lorenzo AB We examine two simple and feasible practical schemes allowing the complete determination of any quantum measuring arrangement. This is illustrated with the example of parity measurement.
