    "abstract": "The multiphoton states generated by high-gain spontaneous parametric\ndown-conversion (SPDC) in presence of large losses are investigated\ntheoretically and experimentally. The explicit form for the two-photon output\nstate has been found to exhibit a Werner structure very resilient to losses for\nany value of the gain parameter, g. The theoretical results are found in\nagreement with the experimental data. The last ones are obtained by quantum\ntomography of the state generated by a high-gain SPDC.",
