Protecting quantum correlations in presence of generalised amplitude damping channel: the two-qubit case [PDF]
Journal of Physics A: Mathematical and Theoretical, 2019 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 ...

Entanglement-assisted capacities of time-correlated amplitude-damping channel [PDF]
, 2013 We calculate the information capacities of a time-correlated amplitude-damping channel, provided the sender and receiver share prior entanglement. Our analytical results show that the noisy channel with zero capacity can transmit information if it has finite memory.

Fidelity recovery scheme for quantum teleportation in amplitude damping channel
Acta Physica Sinica, 2015 During the course of quantum teleportation in amplitude damping channel, the quantum Bell entanglement state will suffer a de-coherence, which will lead to the quality decrease of quantum teleportation, or even communication failure. To overcome this influence, we propose a method to compensate for the de-coherence of Bell entanglement state.

Bounding the quantum capacity with flagged extensions [PDF]
Quantum, 2022 In this article we consider flagged extensions of convex combination of quantum channels, and find general sufficient conditions for the degradability of the flagged extension.

Analysis of Decoherence in Linear and Cyclic Quantum Walks
Optics, 2021 We theoretically analyze the case of noisy Quantum walks (QWs) by introducing four qubit decoherence models into the coin degree of freedom of linear and cyclic QWs.

Simple Non-Markovian Microscopic Models for the Depolarizing Channel of a Single Qubit [PDF]
, 2012 The archetypal one-qubit noisy channels ---depolarizing, phase-damping and amplitude-damping channels--- describe both Markovian and non-Markovian evolution.
