    "abstract": "We address the distribution of quantum information among many parties in the\npresence of noise. In particular, we consider how to optimally send to m\nreceivers the information encoded into an unknown coherent state. On one hand,\na local strategy is considered, consisting in a local cloning process followed\nby direct transmission. On the other hand, a telecloning protocol based on\nnonlocal quantum correlations is analyzed. Both the strategies are optimized to\nminimize the detrimental effects due to losses and thermal noise along the\npropagation. The comparison between the local and the nonlocal protocol shows\nthat telecloning is more effective than local cloning for a wide range of noise\nparameters. Our results indicate that nonlocal strategies can be more robust\nagainst noise than local ones, thus being suitable candidates to play a major\nrole in quantum information networks.",
