摘要: We propose a scheme for teleportation of an unknown $N$-atom state using a two-atom entangled state within a cavity QED and show the feasibility in experiment. Our scheme does not involve the Bell-state measurement and is insensitive to the cavity decay, which is important from the experimental point of view. Another feature of the scheme is that teleporting a N-atom state just requires a small amount of entanglement (i.e. a two-atom entangled state) and less classical bits (two bits).
