| Abstract: | Continious variables quantum teleportation of cat states are studied.The relationships between teleportation's fidelity and the squeezed degree of quantum channel,magnifying coefficient of classical channel of the teleported steps and characteristics of the cat states themselves are discussed by quantum measurements theory.Optimized fidelity of quantum teleportation of the cat states light fields are given by some corresponding physical conditions. |
