Dynamics of entanglement of two dipole-coupled Josephson qubits interacting with two lossless resonators

In the present paper we investigated the dynamics of two dipole-coupled superconducting qubits prepared in an entangled state and interacting with two modes of the vacuum electromagnetic fields of two independent resonators. It is shown that the dipole-dipole interaction of qubits is an effective mechanism for the stabilization of qubits entanglement.
