Teleportation of aTripartite Squeezed Entangled State Via EPR Entangled State with Continuous Variables

摘要

A scheme for teleporting an arbitrary tripartite entangled state is proposed when three bipartite entangled states (vertical bar eta >) with continuous variables are used as quantum channels. Quantum teleportation can be carried out successfully if the receiver adopts an appropriate unitary transformation. The calculation is greatly simplified by virtue of the Schmidt decompositions of both tripartite entangled state vertical bar p (t) ,chi (2),chi (3)> and vertical bar eta >. Any tripartite state which can be expanded in terms of vertical bar p (t) ,chi (2),chi (3)> may be teleported in this way due to the completeness of |vertical bar p (t) ,chi (2),chi (3)>.
