Abstract

We advocate a simple multipole expansion of the polarization 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.

Quantum versus classical polarization states: when multipoles count

Sanchez-Soto, L., Klimov, A., de la Hoz, P. +1 more

We advocate a simple multipole expansion of the polarization density matrix. The resulting multipoles are used to construct bona fide quasiprobability distributions that appear as a sum of successive moments of the Stokes variables, the first one corresponding to the classical picture on the Poincare sphere. We employ the particular case of the Q function to formulate a whole hierarchy of measures that properly assess higher-order polarization correlations.

Assessing Higher-order Quantum Polarization Correlations using Multipole Expansions

Luis Lorenzo Sánchez-Soto

We use a simple multipole expansion of the polarization density matrix. The resulting multipoles are used to construct quasiprobability distributions that appear as a sum of successive moments of the Stokes variables; the first one corresponding to the classical picture on the Poincaré sphere. In this way we formulate a whole hierarchy of measures that properly assess higher-order polarization correlations.

Unpolarized states and hidden polarization

Pablo de la Hoz, Gunnar G. Bjork, A. B. Klimov +2 more

We 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 is $K\mathrm{th}$-order unpolarized, as it lacks of polarization information to that order. First-order unpolarized states coincide with the corresponding classical ones, whereas unpolarized to any order tally with the quantum notion of fully invariant states. In between these two extreme cases, there is a rich variety of situations that are explored here. The existence of hidden polarization emerges in a natural way in this context.

From polarization multipoles to higher-order coherences

Aaron Z. Goldberg, A. B. Klimov, Hubert de Guise +3 more

We demonstrate that the multipoles associated with the density matrix are truly observable quantities that can be unambiguously determined from intensity moments. Given their correct transformation properties, these multipoles are the natural variables to deal with a number of problems in the quantum domain. In the case of polarization, the moments are measured after the light has passed through two quarter-wave plates, one half-wave plate, and a polarizing beam splitter for specific values of the angles of the wave plates. For more general two-mode problems, equivalent measurements can be performed.

Polarization correlations in quantum optics

Luis Lorenzo Sánchez-Soto, A. B. Klimov, Gunnar G. Bjork +4 more

The standard degree of polarization involves exclusively first-order moments of the Stokes variables. This may be sufficient for most classical problems, but for quantum fields higher-order correlations are crucial. We claim that a complete polarization characterization must involve a whole hierarchy of polarization degrees constructed order by order, as it happens in coherence theory. We present here a second-order degree and determine it experimentally.
