    "abstract": "We give a protocol and criteria for demonstrating unconditional teleportation\nof continuous-variable entanglement (i.e., entanglement swapping). The initial\nentangled states are produced with squeezed light and linear optics. We show\nthat any nonzero entanglement (any nonzero squeezing) in both of two\nentanglement sources is sufficient for entanglement swapping to occur. In fact,\nrealization of continuous-variable entanglement swapping is possible using only\n{\\it two} single-mode squeezed states.",
