Quantum polarization distributions via marginals of quadrature distributions
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 princi...

| Resumo: | 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. |
