Entangled-photon-hole-boosted quantum teleportation of Schrödinger-cat

Kaushik P. Seshadreesan, Jonathan P. Dowling, Girish S. Agarwal
We study the teleportation of non-Gaussian, non-classical Schrodinger-cat states of light using two-mode squeezed vacuum light embedded with Franson's entangled photon holes. We discuss two figures of merit a) the fidelity of teleportation and b) the maximum negativity of the Wigner function at the output. We show that the addition of entangled photon holes to two-mode squeezed vacuum light 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.
