Abstract: We show that an unknown quantum state in phase space can be teleported viathree-mode entanglement generated by continuous variable quantum cloningmachine transformation. Further, proceeding with our teleportation protocolwe are able to improve the fidelity of teleportation obtained by Loock et.al.Phys.Rev.Lett. 84, 34822000. Also we study here the entanglement betweenthe two output copies from cloning machine.
