Degradability of Fermionic Gaussian Channels — Eliška Greplová1,2 and •Géza Giedke1,3 — 1Max-Planck-Institut für Quantenoptik, H.-Kopfermann-Str 1, D-85748 Garching — 2Aarhus University, Ny Munkegade 120, DK-8000 Aarhus C — 3Donostia International Physics center, Paseo M. de Lardizabal 4, E-20018 San Sebastian
We study the degradability of fermionic Gaussian channels. We derive a simple standard form that allows the characterization of all degradable and antidegradable fermionic Gaussian channels. We also provide a full weak-degradability classification of these channels. Consequences for the quantum capacity of those channels are discussed.
