    "abstract": "We show how to generate bilinear (quadratic) Hamiltonians in cavity quantum\nelectrodynamics (QED) through the interaction of a single driven three-level\natom with two (one) cavity modes. With this scheme it is possible to generate\none-mode mesoscopic squeezed superpositions, two-mode entanglements, and\ntwo-mode squeezed vacuum states (such the original EPR state), without the need\nfor Ramsey zones and external parametric amplification. The degree of squeezing\nachieved is up to 99% with currently feasible experimental parameters and the\nerrors due to dissipative mechanisms become practically negligible.",
