Enhanced Superdense Coding over Correlated Amplitude Damping Channel [PDF]
Entropy, 2019 Quantum channels with correlated effects are realistic scenarios for the study of noisy quantum communication when the channels are consecutively used. In this paper, superdense coding is reexamined under a correlated amplitude damping (CAD) channel. Two

Information-theoretic aspects of the generalized amplitude-damping channel [PDF]
Physical Review A, 2020 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

Average steered coherence in correlated amplitude damping channel
Results in Physics, 2022 The combined effects of memory effects due to correlated actions of the amplitude damping channel on two qubits and temporal correlations in the time evolution of each qubit on the average steered coherence (ASC) are explored.

Protecting steered coherence in squeezed generalized amplitude damping channel with memory
Results in Physics, 2023 We investigate the average steered coherence (ASC) and maximal steered coherence (MSC) of two qubits in a squeezed generalized amplitude damping channel modeled by a squeezed thermal bath with dissipation and memory. By considering the input Bell states,

Bounds on amplitude-damping-channel discrimination [PDF]
Physical Review A, 2021 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.

Protecting quantum correlations in presence of generalised amplitude damping channel: the two-qubit case [PDF]
Journal of Physics A: Mathematical and Theoretical, 2020 Any kind of quantum resource useful in different information processing tasks is vulnerable to several types of environmental noise. Here we study the behaviour of quantum correlations such as entanglement and steering in two-qubit systems under the ...

On the Entropy Gain Under the Action of the Amplitude Damping Channel on Qutrit [PDF]
Journal of Russian Laser Research, 2014 After realizing qutrit in the form of a bipartite system, we estimate from below the entropy gain under the action of the amplitude damping channel.
