Abstract

We propose a setup for teleportation of continuous quantum variables which is optimized for teleportation of squeezed coherent states. Our scheme is a modified version of the original setup proposed by Braunstein and Kimble [Phys. Rev. Lett. 80, 869, 1998] and it involves an unbalanced beam splitter on the sender's side and a single mode squeezer on receiver's side. We show that the quality of the teleportation can be evaluated by means of a fidelity of entanglement swapping and we prove that our modified setup and the original Braunstein-Kimble setup are equivalent with respect to this fidelity measure.
