Manipulation of qudits in optical tables is a difficult and nonscalable task.The use of integrated optical circuits opens new possibilities for thegeneration, manipulation, and characterization of high dimensional statesbesides the ease of transmission of these states through an optical fiber. Inthis work we propose photonic circuits to perform minimum quantum statetomography of path qudits and show how to determine all the constituentsparameters of these circuits (beam splitters and phase shifters). Ourstrategies were based on the symmetries of the involved POVMs (positiveoperator-valued measures) suggested for minimum tomography and allowed us toobtain interferometers smaller than those obtained by other already knownmethods. The calculations of the transmittances and reflectivities of the beamsplitters were made using the definition of probability operators in extendedHilbert spaces and the application of Naimark's theorem. The employment ofequidistant states for the definition of the POVM elements allowed us todevelop a recipe applicable to the tomography of qudits of any dimension,generalizing our scheme.
