Generalized Bell states generation in a parametrically excited nonlinear coupler
A. Kowalewska-Kudłaszyk, W. Leoński, Jan Peřina · Physica Scripta · 2012
A nonlinear Kerr-like coupler with parametric interaction is considered. It is shown that such a system can be treated as nonlinear quantum scissors enabling the generation of generalized Bell states. Moreover, the influence of the external reservoir on entanglement formation and its survival is considered.
