【Abstract】 This article discusses an alternative scheme to generate a multi-atom entangled W state in cavity QED via Raman transitions.The present scheme does not involve cavity-photon population during the operation and thus is insensitive to the cavity decay.On the other hand,we have also indicated that the scheme is easy to implement from the experimental point of view.更多还原
