    "abstract": "Noisy teleportation of nonclassical quantum states via a two-mode\nsqueezed-vacuum state is studied with the completely positive map and the\nGlauber-Sudarshan $P$-function. Using the nonclassical depth as a measure of\ntransmission performance, we compare the teleportation scheme with the direct\ntransmission through a noisy channel. The noise model is based on the coupling\nto the vacuum field. It is shown that the teleportation channel has better\ntransmission performance than the direct transmission channel in a certain\nregion. The bounds for such region and for obtaining the nonvanished\nnonclassicality of the teleported quantum states are also discussed. Our model\nshows a reasonable agreement with the observed teleportation fidelity in the\nexperiment by Furusawa et al. [Science {\\bf 282}, 706 (1998)]. We finally\nmention the required conditions for transmitting nonclassical features in real\nexperiments.",
