Query: Non-Gaussian entangled states and quantum teleportation of
  Schr\"odinger-cat states   In continuous-variable quantum information, non-Gaussian entangled states
that are obtained from Gaussian entangled states via photon subtraction are
known to contain more entanglement. This makes them better resources for
quantum information processing protocols, such as, quantum teleportation. We
discuss the teleportation of non-Gaussian, non-classical Schr\"odinger-cat
states of light using two-mode squeezed vacuum light that is made non-Gaussian
via subtraction of a photon from each of the two modes. We consider the
experimentally realizable cat states produced by subtracting a photon from the
single-mode squeezed vacuum state. We discuss two figures of merit for the
teleportation process, a) the fidelity, and b) the maximum negativity of the
Wigner function at the output. We elucidate how the non-Gaussian entangled
resource lowers the requirements on the amount of squeezing necessary to
achieve any given fidelity of teleportation, or to achieve negative values of
the Wigner function at the output.
