We propose a formal resource-theoretic approach to assess the coherence between partially polarized electromagnetic fields. From this framework, we identify two resource theories for the vectorial coherence: polarization-sensitive coherence and polarization-insensitive coherence. For each theory, we find the set of incoherent states and a class of operations that preserve this set (i.e., the incoherent operations). Both resource theories are endowed with a certain preorder relation that…

Optical coherence engineering in the polarization and spatial degrees of freedom

ABSTRACT We report a method to synthesize the complete range of arbitrary combinations of coherences independently in both the polarization and spatial degrees of freedom (DoFs) by utilizing energy

Complementarity relations for quantum coherence

Various measures have been suggested recently for quantifying the coherence of a quantum state with respect to a given basis. We first use two of these, the l_1-norm and relative entropy measures, to

Coherence polarization filtering and relation with intrinsic degrees of coherence.

It is demonstrated for stationary fields that when the polarization state of the electric field can be modified arbitrarily the maximal value of the modulus of the degree of coherence proposed by

Two-point optical coherency matrix tomography.

TLDR
This work describes a systematic sequence of cascaded spatial and polarization projective measurements that are sufficient to tomographically reconstruct G, the 4×4 coherency matrix of an electromagnetic field that encodes the joint polarization-spatial-field correlations.

Phase correlations and optical coherence.

TLDR
It is seen that some of the recently introduced degrees of coherence regarding the phase correlations of the optical field are straightforwardly related to the limits of complete dependence and complete independence of phases, which were used by Zernike in 1938.

Linear algebraic theory of partial coherence: discrete fields and measures of partial coherence

TLDR
A scalar measure of the degree of partial coherence of an optical field which is zero for complete incoherence and unity for full coherence is defined.

Demonstration of an optical-coherence converter

Studying the coherence of an optical field is typically compartmentalized with respect to its different physical degrees of freedom (DoFs)—spatial, temporal, and polarization. Although this

Quantifying coherence.

TLDR
A rigorous framework for the quantification of coherence is introduced and classes of functionals that satisfy defining conditions that satisfy these conditions are identified and other, at first glance natural quantities, that do not qualify as coherence measures.
