    "abstract": "We address the propagation of twin-beam of radiation through Gaussian\nphase-sensitive channels, i.e. noisy channels with squeezed fluctuations. We\nfind that squeezing the environment always reduces the survival time of\nentanglement in comparison to the case of simple dissipation and thermal noise.\nWe also show that the survival time is further reduced if the squeezing phase\nof the fluctuations is different from the twin-beam phase.",
