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 study the phenomenon of localization and delocalization in a circuit-QED network with connectivity varying from finite-range coupling to all-to-all coupling. find fascinating interplay between interactions connectivity. In particular, we consider (i) harmonic, (ii) Jaynes-Cummings, (iii) Bose-Hubbard networks. start initial condition where one nodes is populated then let it evolve time. The ...
