Conjugate degradable channels: A new class of quantum channels with a tractable quantum capacity formula
Kamil Bradler
Conjugate degradable channels are channels whose quantum capacity is calculable. They were defined and studied in [1] where, however, only channels that are both degradable and con…

Coherent information of one-mode Gaussian channels -- the general case of nonzero added classical noise
Kamil Bradler
We prove that whenever the coherent information of a one-mode Gaussian channel is non-zero its supremum is achieved for the infinite input power. This is a well established fact fo…

Black holes as bosonic Gaussian channels
Kamil Bradler, Christoph Adami
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 classifi…
