Teleportation of a two-particle four-component squeezed vacuum state by linear optical elements

Abstract

We present a linear optical scheme for achieving a unity fidelity teleportation of a two-particle four-component squeezed vacuum state using two entangled squeezed vacuum states as quantum channel. The devices used are beam splitters and ideal photon detectors capable of distinguishing between odd and even photon numbers. Moreover, we also obtain the success probability of the teleportation scheme. © 2009 Chinese Optics Letters.
