We consider a model of two identical atoms coupled to a single-mode cavity. When in atom-field strong coupling regime, the entanglement of the two atoms with spontaneous emission should be investigated beyond rotating-wave approximation. In order to improve the entanglement of the two atoms, some typical feedbacks based on quantum jump are attempted to impose on the atoms. The result of numerical simulations shows that an appropriate feedback control can improve the entanglement.
Keywords:entanglement control; non-perturbative master equation; quantum-jump based feedback; strong coupling
