چکیده
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 calculation show that separable states, nonlinearity can lead to significant increase maximum degree qubit entanglement. It shown entangledstates intense fields, taking into account nonlinearities leads stabilization contributes disappearance effect sudden death qubits.

Entanglement sharing in the two-atom Tavis-Cummings model
Individual members of an ensemble of identical systems coupled to a common probe can become entangled with one another, even when they do not interact directly. We investigate how this type of multipartite entanglement is generated in the context of a system consisting of two two-level atoms resonantly coupled to a single mode of the electromagnetic field. The dynamical evolution is studied in ...
متن کاملThermal Entanglement in the Two-qubit Heisenberg Xyz Model
We study the entanglement of a two-qubit one dimensional XYZ Heisenberg chain in thermal equilibrium at temperature T. We obtain an analytical expression for the concurrence of this system in terms of the parameters of the Hamiltonian and T. We show that depending on the relation among the coupling constants it is possible to increase the amount of entanglement of the system increasing its anis...
متن کاملThe entanglement character between atoms in the non - degenerate two photons Tavis - Cummings model
The entanglement character including the so-called sudden death effect between atoms in the non-degenerate two photons Tavis-Cummings model is studied by means of concurrence. The results show that the so-called sudden death effect occurs only for some kind of initial states. In other words, the phenomenon is sensitive to the initial conditions. One can expect the resurrection of the original e...
متن کاملEntanglement in the adiabatic limit of a two - atom Tavis - Cummings model
We study the adiabatic limit for the sequential passage of atoms through a high-Q cavity, in the presence of frequency chirps. Despite the fact that the adiabatic approximation might be expected to fail, we were able to show that for proper choice of Stark-pulses this is not the case. Instead, a connection to the resonant limit is established, where the robust creation of entanglement is demons...
متن کاملQuantum Control of Two-qubit Entanglement Dissipation
We investigate quantum control of the dissipation of entanglement under environmental decoherence. We show by means of a simple two-qubit model that standard control methods coherent or open-loop control will not in general prevent entanglement loss. However, we propose a control method utilising a Wiseman-Milburn feedback/measurement control scheme which will effectively negate environmental e...
