    "abstract": "A complete degradability analysis of one-mode Gaussian Bosonic channels is\npresented. We show that apart from the class of channels which are unitarily\nequivalent to the channels with additive classical noise, these maps can be\ncharacterized in terms of weak- and/or anti-degradability. Furthermore a new\nset of channels which have null quantum capacity is identified. This is done by\nexploiting the composition rules of one-mode Gaussian maps and the fact that\nanti-degradable channels can not be used to transfer quantum information.",
