One-mode Bosonic Gaussian channels: a full weak-degradability classification
A complete weak-degradability analysis of one-mode Gaussian Bosonic channels is performed. A new set of channels which have null quantum capacity is identified. Due to their relatively simple structure Gaussian channels [1] provide an ideal theoretical playground for the study of quantum communication protocols [2]. Bounds and, in some cases, explicit values for the classical [3] or quantum [4]...
متن کاملMulti-mode bosonic Gaussian channels
A complete analysis of multi-mode bosonic Gaussian channels is proposed. We clarify the structure of unitary dilations of general Gaussian channels involving any number of bosonic modes and present a normal form. The maximum number of auxiliary modes that is needed is identified, including all rank deficient cases, and the specific role of additive classical noise is highlighted. By using this ...
متن کاملOne-mode quantum Gaussian channels
A classification of one-mode Gaussian channels is given up to canonical unitary equivalence. A complementary to the quantum channel with additive classical Gaussian noise is described providing an example of onemode Gaussian channel which is neither degradable nor anti-degradable. 1 The canonical form For a mathematical framework of linear Bosonic system used in this note the reader is referred...
متن کاملEvaluating capacities of bosonic Gaussian channels
We show how to compute or at least to estimate various capacity-related quantities for bosonic Gaussian channels. Among these are the coherent information, the entanglement-assisted classical capacity, the one-shot classical capacity, and a quantity involving the transpose operation, shown to be a general upper bound on the quantum capacity, even allowing for finite errors. All bounds are expli...
متن کاملBlack holes as bosonic Gaussian channels
We identify the quantum channels corresponding to the interaction of a Gaussian quantum state with an already formed Schwarzschild black hole. Using recent advances in the classification of one-mode bosonic Gaussian channels, we find that (with one exception) the black hole Gaussian channels lie in the nonentanglement breaking subset of the lossy channels CðlossÞ, amplifying channels CðampÞ and...
