Extremal states for photon number and quadratures as gauges for nonclassicality
Z. Hradil, J. Rehacek, P. de la Hoz +2
Rotated quadratures carry the phase-dependent information of the electromagnetic field, so they are somehow conjugate to the photon number. We analyze this noncanonical pair, findi…
Unpolarized states and hidden polarization
P. de la Hoz, G. Bjork, A. B. Klimov +2
We capitalize on a multipolar expansion of the polarisation density matrix, in which multipoles appear as successive moments of the Stokes variables. When all the multipoles up to…
Classical distinguishability as an operational measure of polarization
G. Bjork, H. de Guise, A. B. Klimov +2
We 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 distanc…
Multipolar hierarchy of efficient quantum polarization measures
P. de la Hoz, A. B. Klimov. G. Bjork, Y. -H. Kim +4
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…
Lost and found: the radial quantum number of Laguerre-Gauss modes
E. Karimi, R. W. Boyd, P. de la Hoz +6
We introduce an operator linked with the radial index in the Laguerre-Gauss modes of a two-dimensional harmonic oscillator in cylindrical coordinates. We discuss ladder operators f…
