    "abstract": "We address the generation of fully inseparable three-mode entangled states of\nradiation by interlinked nonlinear interactions in $\\chi^{(2)}$ media. We show\nhow three-mode entanglement can be used to realize symmetric and asymmetric\ntelecloning machines, which achieve optimal fidelity for coherent states. An\nexperimental implementation involving a single nonlinear crystal where the two\ninteractions take place simultaneously is suggested. Preliminary experimental\nresults showing the feasibility and the effectiveness of the interaction scheme\nwith seeded crystal are also presented.",
