Enhancing the information of nonlinear SU(1, 1) quantum systems interacting with a two-level atom

Abstract The effect of nonlinearity, initial atomic state, and different resonance cases on the interaction between nonlinear SU (1, 1) quantum states a two-level atom is discussed. optimal behaviours decoherence, entanglement coherence are predicted via using skew information, tomographic entropy, relative entropy coherence, respectively. It shown that detuning parameter has destructive consequently if system regulated in ideal systems. For systems, ability to suppress decay induced by may be increased preparing state its excited state.
