In this work, we have studied the dynamics of entanglement two identical superconducting qubits resonantly interacting with one-mode field a coplanar microwave cavity without loss through single-photon transitions in presence third- and fifth-order nonlinearities. Based on solution equation evolution system for Fock initial states field, criterion negativity is calculated. The results calculati...

Analog quantum simulation---the technique of using one experimentally well-controlled physical system to mimic the behavior another---has quickly emerged as most promising near-term strategies for studying strongly correlated many-body systems. In particular, systems interacting photons, realizable in solid-state cavity and circuit QED frameworks, example, hold tremendous promise study nonequil...

We derive an analytical approximate solution of the time-dependent state vector in terms material Bell states and coherent field for a generalized two-atom Tavis-Cummings model with nonlinear intensity-dependent matter-field interaction. Using this solution, we obtain simple expressions atomic concurrence purity order to study entanglement system at specific interaction times. show how implemen...
