    "abstract": "An interaction scheme involving nonlinear $\\chi^{(2)}$ media is suggested for\nthe generation of phase-coherent states (PCS). The setup is based on parametric\namplification of vacuum followed by up-conversion of the resulting twin-beam.\nThe involved nonlinear interactions are studied by the exact numerical\ndiagonalization. An experimentally achievable working regime to approximate PCS\nwith high conversion rate is given, and the validity of parametric\napproximation is discussed.",
