Polarization-squeezed triphoton states and their Wigner representation on the Poincaré sphere
Lynden K. Shalm, Robert B. A. Adamson, Aephraim M. Steinberg · 2008
We present reconstructions of Wigner distributions for the polarization state of three indistinguishable photons on the generalized Poincare sphere. We study a variety of states including coherent, phase and NOON states.
