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

Quantum teleportation of shared quantum secret in amplitude-damping channel. [PDF]
PLoS ONEWe give the detailed processes for sharing a four-qubit pure entangled state as quantum channel in amplitude damping (AD) network channel via entanglement compensation.We propose a secure (2,2)-type quantum teleportation (QT) scheme based on this AD ...

Protecting entanglement from correlated amplitude damping channel using weak measurement and quantum measurement reversal [PDF]
, 2016 Based on the quantum technique of weak measurement, we propose a scheme to protect the entanglement from correlated amplitude damping decoherence. In contrast to the results of memoryless amplitude damping channel, we show that the memory effects play a ...

Classical and quantum capacities of a fully correlated amplitude damping channel [PDF]
, 2013 We study information transmission over a fully correlated amplitude damping channel acting on two qubits. We derive the single-shot classical channel capacity and show that entanglement is needed to achieve the channel best performance.

Information-theoretic aspects of the generalized amplitude-damping channel [PDF]
, 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
