Abstract

We investigate the entanglement properties of the Kerr-down conversion system with two entanglement criteria. We first obtain the exact analytic solutions for operators under certain condition. Using the exact analytic solutions, we show that the azimuth angle is independence of linear interaction; while the polar angle is independence of nonlinear interaction. By characterizing the degree of entanglement with two criteria, we see that the entanglement properties of the Kerr-down conversion system can be controlled by adjusting the nonlinear interaction and the linear interaction.
