Björk, G. ; de Guise, H. ; Klimov, A.B. ; Hoz Iglesias, Pablo de la ; Sánchez Soto, Luis Lorenzo | American Physical Society | 2014-07-23We put forward an operational degree of polarization that can be extended in a natural way to fields whose wave fronts are not necessarily planar. This measure appears as a distance from a state to the set of all of its polarization-transformed [...]texto impreso
Björk, G. ; Klimov, A. B. ; Hoz Iglesias, Pablo de la ; Grassl, M. ; Leuchs, G. ; Sánchez Soto, Luis Lorenzo | American Physical Society | 2015-09-01The characterization of quantum polarization of light requires knowledge of all the moments of the Stokes variables, which are appropriately encoded in the multipole expansion of the density matrix. We look into the cumulative distribution of th[...]texto impreso
Hoz Iglesias, Pablo de la ; Björk, G. ; Klimov, A. B. ; Leuchs, G. ; Sánchez Soto, Luis Lorenzo | American Physical Society | 2014-10-15We capitalize on a multipolar expansion of the polarization density matrix, in which multipoles appear as successive moments of the Stokes variables. When all the multipoles up to a given order K vanish, we can properly say that the state isKth-[...]
