| Abstract: | A scheme has been proposed for generating the macroscopicentanglement between the mesoscopic squeezed vacuum states and mesoscopiccoherent states by considering both the two-photon interaction and thesingle photon interaction of N two-level atoms in cavities with highquality factor assisted by a strong driving field. Moreover, we derivethe dissipative interaction models for single photon interaction andtwo-photon interaction, respectively. The corresponding analyticalexpressions of the fidelities can be given. Our scheme can be realized inthe current techniques on the cavity QED. |
