Teleportation of two-mode squeezed vacuum states

Abstract

Abstract: The teleportation of two-mode continuous variables is performed by using two two-mode squeezed vacuum states which are served as quantum channel. The average fidelity and the probability density are calculated for teleportation of a two-mode squeezed vacuum state. The results indicate that increased squeezing of teleported state will lead to a loss of fidelity. The probability density of measuring result consists of the product of two bivariate normal density functions, and it shows that when the average fidelity goes up, the probability of obtaining large measurement value also increases.

Key words: quantum optics, quantum teleportation, squeezed vacuum states, continuous variables
