    "abstract": "We present a proposal for the production of longer-lived mesoscopic\nsuperpositions which relies on two requirements: parametric amplification and\nsqueezed vacuum reservoir for cavity-field states. Our proposal involves the\ninteraction of a two-level atom with a cavity field which is simultaneously\nsubjected to amplification processes.",
