Distance-based degrees of polarization for a quantum field
TL;DR: In this paper, the degree of polarization of a quantum state is defined as its distance to the set of unpolarized states, and two different candidates of distance, namely the Hilbert-Schmidt and the Bures metric, are proposed.

On the distribution of 1550-nm photon pairs efficiently generated using a periodically poled lithium niobate waveguide
TL;DR: In this paper, the spontaneous parametric down-conversion process was used to generate 1550-nm photon pairs in a periodically poled lithium niobate waveguide using the spontaneous up-down conversion process.

TL;DR: An operational degree of polarization in terms of the variance of the Stokes vector minimized over all the directions of the Poincaré sphere is proposed and argued that a comprehensive quantum characterization of polarization properties requires a whole hierarchy of higher-order degrees.

TL;DR: In this article, a complete polarization characterization of any quantum state of two orthogonal polarization modes is presented, which requires measurements of the photon number in both modes and linear optics.

Comprehensive experimental test of quantum erasure
TL;DR: In this paper, the authors used a partial polarizer to vary the degree of entanglement between the object and the probe to test quantum erasure under a number of different experimental conditions.
