摘      要：The generalized continuous variable two-mode entangled state |? is proposed by using the technique of integration within an ordered product (IWOP) of operators. The characteristics of this new entangled representation and its application in quantum teleportation are analyzed in detail. These results indicate that such real parameters |? indeed make up a new entangled representation owing to its completeness and orthogonal relation. By employing the |? as quantum transmission channel, the teleportation of any single-mode quantum state 3 |ψ3 can be realized by a unitary transformation.
