Assessing the Polarization of a Quantum Field from Stokes Fluctuation

Abstract

We propose an operational degree of polarization in terms of the variance of the projected Stokes vector minimized over all the directions of the Poincaré sphere. We examine the properties of this degree and show that some problems associated with the standard definition are avoided. The new degree of polarization is experimentally determined using two examples: a bright squeezed state and a quadrature squeezed vacuum.
