Opis:: A scheme is presented to generate an entangled atomic state, for which the quantum phase affects the atom-atom entanglement when the atom interacts with external light fields. The quantum phase enhances the entanglement and extends the time that the system stays in stronger entanglement state or the phase makes the system more robust. It is also shown that the quantum phase is able to delay the entanglement sudden death and hasten the entanglement revival.

Opis:: In this paper, we present a proper quantum system to perform different tasks of quantum information processing with optimal conditions. We study the populations, entanglement, and nonclassical properties of a system consisting of three level atom interacting with a nonlinear Kerr medium field constructed in the framework of generalized Heisenberg algebra. We quantify these quantities in terms of different parameters involved in the whole system considering the case of moving and stationary atom in the real experimental meaning of the coupling constant. The nonlinearity introduced by these kinds of fields play a useful role to create high amount of entanglement during the time evolution. Interestingly, the relationship between the degree of nonlinearity and robust of entanglement is explored in this present model.
