Multipolar hierarchy of efficient quantum polarization measures
arXiv:1401.3544 · doi:10.1103/PhysRevA.88.063803
Abstract
We advocate a simple multipole expansion of the polarisation density matrix. The resulting multipoles appear as successive moments of the Stokes variables and can be obtained from feasible measurements. In terms of these multipoles, we construct a whole hierarchy of measures that accurately assess higher-order polarization fluctuations.
