Quantum capacity analysis of multi-level amplitude damping channels [PDF]
Communications Physics, 2021 Estimating the capacity of quantum channels is relevant to understand at which rate quantum information can be exchanged. Here, the authors introduce multi-level amplitude damping channels that generalize the qubit amplitude damping noise model, analyse ...

Resonant Multilevel Amplitude Damping Channels [PDF]
Quantum, 2023 We introduce a new set of quantum channels: resonant multilevel amplitude damping (ReMAD) channels. Among other instances, they can describe energy dissipation effects in multilevel atomic systems induced by the interaction with a zero-temperature ...
