We study three independent pairs of Jaynes–Cummings systems such that two atoms might be correlated with each other but the third atom is uncorrelated rest. investigate conditions under which these may become genuinely entangled. find this task impossible if cavity interacting share classical correlations any cavity. observe atomic state can genuine multipartite entangled, at least atom, highly...

We calculate the cavity-field distribution in Wigner representation for two-photon resonance of weakly driven Jaynes-Cummings (JC) oscillator its strong-coupling limit. Using an effective four-level system, we analytically demonstrate presence steady-state and transient bimodality which breaks azimuthal symmetry phase space. The two peaks are located at opposite positions do not correspond to a...

We introduce a dynamical system that instead of exchanging single photon as in the atomic usual Jaynes-Cummings model (JCM), it exchanges squeezed coherent photon. Accordingly, creation and annihilation operators JCM are replaced by states, respectively. This transformation generates Hamiltonian modifies includes terms usually omitted when making rotating-wave approximation and, addition, intro...

In this paper we consider the two atoms Tavis–Cummings model and give an explicit form to the solution of this model which will play a central role in quantum computation based on atoms of laser–cooled and trapped linearly in a cavity. We also present a problem of three atoms Tavis–Cummings model which is related to the construction of controlled–controlled NOT operation (gate) in quantum compu...
