We present a proposal for the production of longer-lived mesoscopic superpositions which relies on two requirements: parametric amplification and a squeezed vacuum reservoir for cavity-field states. Our proposal involves the interaction of a two-level atom with a cavity field which is simultaneously subjected to amplification processes.
