Abstract
We investigate the interplay between quantum correlations, quantified by the global quantum discord and quantum Fisher information in a multi two-level system interacting with a single mode Fock field. Our model incorporates Kerr like non linearity effects, parametric amplification and intrinsic decoherence.
