Query: Robust high-fidelity teleportation of an atomic state through the
  detection of cavity decay   We propose a scheme for quantum teleportation of an atomic state based on the
detection of cavity decay. The internal state of an atom trapped in a cavity
can be disembodiedly transferred to another atom trapped in a distant cavity by
measuring interference of polarized photons through single-photon detectors. In
comparison with the original proposal by S. Bose, P.L. Knight, M.B. Plenio, and
V. Vedral [Phys. Rev. Lett. 83, 5158 (1999)], our protocol of teleportation has
a high fidelity of almost unity, and inherent robustness, such as the
insensitivity of fidelity to randomness in the atom's position, and to
detection inefficiency. All these favorable features make the scheme feasible
with the current experimental technology.
