Abstract: | A scheme has been proposed for generating the macroscopic
entanglement between the mesoscopic squeezed vacuum states and mesoscopic
coherent states by considering both the two-photon interaction and the
single photon interaction of N two-level atoms in cavities with high
quality factor assisted by a strong driving field. Moreover, we derive
the dissipative interaction models for single photon interaction and
two-photon interaction, respectively. The corresponding analytical
expressions of the fidelities can be given. Our scheme can be realized in
the current techniques on the cavity QED. |
