摘要: We present a scheme for realizing probabilistic teleportation of an unknown $N$-atom state via cavity QED. This scheme requires only a nonmaximally entangled pair to be used as a quantum channel, so the requirement of entanglement is reduced. In addition, 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. If the quantum channel is a two-atom maximally entangled state, teleportation of an unknown $N$-atom state can be realized by a simpler scheme via cavity QED.
