    "abstract": "We study creation of bi- and multipartite continuous variable entanglement in\nstructures of coupled quantum harmonic oscillators. By adjusting the\ninteraction strengths between nearest neighbors we show how to maximize the\nentanglement production between the arms in a Y-shaped structure where an\ninitial single mode squeezed state is created in the first oscillator of the\ninput arm. We also consider the action of the same structure as an approximate\nquantum cloner. For a specific time in the system dynamics the last oscillators\nin the output arms can be considered as imperfect copies of the initial state.\nBy increasing the number of arms in the structure, multipartite entanglement is\nobtained, as well as 1 to M cloning. Finally, we are considering configurations\nthat implement the symmetric splitting of an initial entangled state. All\ncalculations are carried out within the framework of the rotating wave\napproximation in quantum optics, and our predictions could be tested with\ncurrent available experimental techniques.",
