Abstract

I consider the teleportation of superposition of coherent states  and  using beam splitters and phase shifters. I propose some modifications which consist of writing the output state as a superposition of the vacuum state and nonzero even photon state, which allow for an almost perfect teleportation to be achieved for an appreciable mean number of photons.

 

Keywords: Entangled states, fidelity, teleportation
