Abstracts

EN

A scheme is presented to generate an entangled atomic state, for which the quantum phase affects the atom-atom entanglement when the atom interacts with external light fields. The quantum phase enhances the entanglement and extends the time that the system stays in stronger entanglement state or the phase makes the system more robust. It is also shown that the quantum phase is able to delay the entanglement sudden death and hasten the entanglement revival.
