This work has been supported by Project No. FIS2004-01814 of the Spanish Dirección General de Investigación del Ministerio de Educación y Ciencia.We derive quantum polarization distributions on the Poincare sphere for two-mode fields as suitable marginals of the standard s-ordered quadrature distributions that include the Wigner function. We compare them with previously introduced distributions directly defined on the sphere from first principles. We apply this approach to some relevant field states such as coherent and number states.engjournal articlehttp://dx.doi.org/10.1103/PhysRevA.71.053801http://journals.aps.org/open access535Discrete wigner functionQuasi-probability distributionsState reconstructionNonclassical statesCoherent statesDensity-matrixQuasiprobability distributionsPhase distributionsSqueezed statesSpin statesÓptica (Física)2209.19 Óptica Física
