    "abstract": "The realization of nonclassical states is an important task for many\napplications of quantum information processing. Usually, properly tailored\ninteractions, different from goal to goal, are considered in order to\naccomplish specific tasks within the general framework of quantum state\nengineering. In this paper we remark on the flexibility of a cross-Kerr\nnonlinear coupling in hybrid systems as an important ingredient in the\nengineering of nonclassical states. The general scenario we consider is the\nimplementation of high cross-Kerr nonlinearity in cavity-quantum\nelectrodynamics. In this context, we discuss the possibility of performing\nentanglement transfer and swapping between a qubit and a continuous-variable\nstate. The recently introduced concept of entanglement reciprocation is also\nconsidered and shown to be possible with our scheme. We reinterpret some of our\nresults in terms of applications of a generalized Ising interaction to systems\nof different nature.",
