Relationship between the field local quadrature and the quantum discord of a photon-added correlated channel under the influence of scattering and phase fluctuation noise

Francisco A. Dominguez-Serna, Francisco J. Mendieta-Jimenez, Fernando Rojas

We study quantum correlations and discord in a bipartite continuous variable hybrid system formed by linear combinations of coherent states $|\alpha ⟩$ and single photon added cohe…
