摘要：

In this letter we propose a scheme using a two-photon process to teleport an entangled field state of a bimodal cavity to another one without Bell-state measurement The quantum information is stored in a zero- and two-photon entangled state This scheme requires two three level atoms in a ladder configuration two bimodal cavities and selective atomic detectors The fidelity and success probability do not depend on the coefficients of the state to be teleported For convenient choices of interaction times the teleportation occurs with fidelity close to the unity (C) 2010 Elsevier B V All rights reserved
