Query: Central-moment description of polarization for quantum states of light   We present a moment expansion method for the systematic characterization of
the polarization properties of quantum states of light. Specifically, we link
the method to the measurements of the Stokes operator in different directions
on the Poincar\'{e} sphere, and provide a method of polarization tomography
without resorting to full state tomography. We apply these ideas to the
experimental first- and second-order polarization characterization of some
two-photon quantum states. In addition, we show that there are classes of
states whose polarization characteristics are dominated not by their
first-order moments (i.e., the Stokes vector) but by higher-order polarization
moments.
