    "abstract": "We discuss a model comprising two coupled nonlinear oscillators (Kerr-like\nnonlinear coupler) with one of them pumped by an external coherent excitation.\nApplying the method of nonlinear quantum scissors we show that the quantum\nevolution of the coupler can be closed within a finite set of n-photon Fock\nstates. Moreover, we show that the system is able to generate Bell-like states\nand, as a consequence, the coupler discussed behaves as a two-qubit system. We\nalso analyze the effects of dissipation on entanglement of formation\nparametrized by concurrence.",
