# Multi-level Amplitude Damping channels: quantum capacity analysis

@article{Chessa2020MultilevelAD, title={Multi-level Amplitude Damping channels: quantum capacity analysis}, author={Stefano Chessa and Vittorio Giovannetti}, journal={arXiv: Quantum Physics}, year={2020} }

The set of Multi-level Amplitude Damping (MAD) quantum channels is introduced as a generalization of the standard qubit Amplitude Damping Channel to quantum systems of finite dimension $d$. In the special case of $d=3$, by exploiting degradability, data-processing inequalities, and channel isomorphism, we compute the associated quantum and private classical capacities for a rather wide class of maps, extending the set of solvable models known so far. We proceed then to the evaluation of the…
