摘要：
We have investigated the influence of dipole-dipole interaction and initial atomic coherence on the dynamics of two-qubit entanglement. We have considered a model, in which only one atom couples to a quantum electromagnetic field in a finite-Q cavity, since one of them can freely move outside the cavity. We have shown the possibility of disappearance of the entanglement sudden death effect and stabilization of atomic entanglement in the presence of the dipole interaction of qubits.
