ABSTRACT

In this report r we have investigated the effect of the atomic coherence on the entanglement of two artificial atoms (superconducting flux qubits) with Delta -type transitions interacting with thermal field through a nondegenerate two-photon processes taking into account the dipole interaction. It is shown that the entanglement is dependent on the initial atomic state and strength of dipole-dipole interaction. The results also show that the entanglement can be controlled by changing the system parameters, such as relative phases, the amplitudes of the polarized atoms, the mean photon numbers of the two-mode thermal field, and the strength of the dipole interaction. The have derived that the dipole-dipole interaction can produce the appreciable amount of entanglement when artificial atoms to be prepared in specific coherent states.
