摘要：
We present a calculation of the fidelity of a cavity-field state teleported by means of a scheme that requires only two high-Q cavities. Based on current experimental capabilities, we demonstrate the feasibility of our scheme if the mean photon number of the cavity field is on the order of unity, allowing a reasonably accurate teleportation.
