Application of three-mode Einstein-Podolsky -Rosen entangled state with continuous variables to teleportation

摘要

We consider how to teleport two- and three-mode Einstein-Podolsky-Rosen entangled states (|η > and |p_t,χ_2,χ_3 >) via a |p_t,χ_2,χ_3 > quantum channel for continuous variables. Using the complete and orthogonal representation of the entangled states, we can not only find the a complete basis set for the joint measurement but also propose the specific scheme of teleportation. Our calculation can be greatly simplified by using their Schmidt decompositions.
