Information-theoretic aspects of the generalized amplitude-damping channel [PDF]
Physical Review A, 2019 The generalized amplitude damping channel (GADC) is one of the sources of noise in superconducting-circuit-based quantum computing. It can be viewed as the qubit analogue of the bosonic thermal channel, and it thus can be used to model lossy processes in

Bounds on amplitude-damping-channel discrimination [PDF]
Physical Review A, 2020 Amplitude-damping (AD) channels are good models for many physical scenarios, and so the development of protocols to discriminate between them is an important task in quantum information science.

Coherence evolution in two-qubit system going through amplitude damping channel [PDF]
Science China Physics, Mechanics & Astronomy, 2017 In this paper, we analyze the evolution of quantum coherence in a two-qubit system going through the amplitude damping channel. After they have gone through this channel many times, we analyze the systems with respect to the coherence of their output ...
