Query: Rome teleportation experiment analysed in the Wigner representation: the
  role of the zeropoint fluctuations in complete one-photon
  polarization-momentum Bell-state analysis   The Wigner representation of parametric down conversion in the Heisenberg
picture is applied to the study of the Rome teleportation experiment. We
investigate the physical meaning of the zeropoint inputs at the different areas
of the experimental setup. In particular, we establish a quantitative
relationship between the zeropoint sets of modes that are needed for the
preparation of the quantum state to be teleported, the idle channels inside the
one-photon polarization-momentum Bell-state analyser, and the possibility of
performing teleportation of a polarization state whith certainty.
