Query: The role of the non-Gaussianity plays in the enhancement of the fidelity
  in continuous variable quantum teleportation   We investigated the role of non-Gaussianity (nG) plays in the enhancement of
the fidelity in continuous-variable quantum teleportation of ideal Braunstein
and Kimble (BK) protocol for coherent states, theoretically. The
de-Gaussification procedure is realized through subtracting photons on the
two-mode squeezed vacuum state (TMSVs). We find that the high fidelity always
refers to a symmetrical arrangement of photon subtractions on the different
modes of the TMSVs. The non-Gaussian resources demonstrate commendable
superiorities compare with the Gaussian resources only for symmetrical
arrangements of photon subtractions, however, the asymmetrical arrangements do
not. When the total number of photon subtractions be a constant, we find that
the optimal nG procedure prefers the most asymmetrical arrangement of
subtractions. This characteristic is not consistent with the result that the
highest fidelity refers to a symmetrical case. Under the same squeezing
parameter, a higher nG might not always lead to a higher fidelity.
