Abstract

We discuss the continuous variable entanglement swapping using the Wigner function. The sufficient inseparability criterion for continuous variable systems is used to analyse the quantum correlation. Perfect teleportation can be obtained by increasing the degree of squeezing on the entanglement source. Entanglement swapping occurs for any nonzero squeezing in both of the two initial sources if optimal gain is obtained.
