Computer Simulations of Entanglement Dynamics for Nonlinear System

In this paper we discuss the simulation method allowing modeling of quantum unitary dynamics. In particular, we discuss the model of two nonlinear oscillators (nonlinear coupler) excited by an external field as an example of systems exhibiting a possibility of entanglement generation. We show that Bell-like states are generated proving that the numerical method applied can be used as tools of quantum-mechanical simulations leading to interesting results.
