Effects of intrinsic decoherence in multipartite system subjected to Kerr effect and parametric amplification with quantum correlations and estimation
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.
