A scheme has been proposed for generating the macroscopic superpositions and the entanglement between the mesoscopic squeezed
vacuum states by considering the two-photon interaction of N two-level atoms in a dissipative cavity with high quality factor assisted by a strong driving field. A number of multiparty
entangled states between the atoms and the squeezed vacuum states, among the atoms, and among the squeezed vacuum states,
can be prepared by virtue of a specific choice of the cavity detuning and the detuning of applied coherent field under the
dissipation condition. The corresponding analytical expressions of the influence can be given. Moreover, we can also give
a series of macroscopic entangled states between the usual coherent states and the squeezed vacuum states using the combination
of the dissipative one-photon interaction Hamiltonian with the dissipative two-photon interaction Hamiltonian. We also discuss
the experimental feasibility. Our scheme can be realized in the current techniques on the cavity QED. 相似文献
