通过原子间的不同相互作用时间来触发和控制纠缠

he generation of the entanglement between two two-level atoms interacted with the third atom driven by white noise is investigated when the coupling between atoms is modulated by a pulse function. It is found that the initial triggering time and the width of the pulse can generate a peak in the entanglement. There is an optimal width of the pulse that the entanglement can reach a maximum. The asymmetry of the coupling between atoms can generate different entanglement in the system. The multiple triggers can generate multiple peaks in the entanglement. The separation between two peaks is increased as the the width of the pulse is increased.
