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,

Resonant Multilevel Amplitude Damping Channels
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 bosonic environment.

Queue-Channel Capacities with Generalized Amplitude Damping [PDF]
, 2021 The generalized amplitude damping channel (GADC) is considered an important model for quantum communications, especially over optical networks. We make two salient contributions in this paper apropos of this channel. First, we consider a symmetric GAD channel characterized by the parameter $n=1/2,$ and derive its exact classical capacity, by ...

Entanglement Swapping Through The Amplitude Damping Noise Channel [PDF]
Abstract This paper investigates the degradation mechanism of the photon-number-encoded entanglement swapping protocol under the amplitude damping noise channel. By establishing a beam splitter physical model to simulate the energy dissipation process, the evolution density matrix of the input states |ψ⟩ AB = α |00⟩ + β |11⟩ and |ψ⟩ CD =

Quantum capacity analysis of multi-level amplitude damping channels [PDF]
Communications Physics, 2021 AbstractEvaluating capacities of quantum channels is the first purpose of quantum Shannon theory, but in most cases the task proves to be very hard. Here, we introduce the set of Multi-level Amplitude Damping quantum channels as a generalization of the standard qubit Amplitude Damping Channel to quantum systems of finite dimension d.

Genuine entanglement under squeezed generalized amplitude damping channels with memory [PDF]
Chinese Physics B, 2023 We study genuine entanglement among three qubits undergoing a noisy process that includes dissipation, squeezing, and decoherence. We obtain a general solution and analyze the asymptotic quantum states. We find that most of these asymptotic states can be genuinely entangled depending upon the parameters of the channel, memory parameter, and the ...

Quantum Correlation in Squeezed Generalized Amplitude Damping Channels with Memory [PDF]
Scientific Reports, 2019 AbstractA squeezed generalized amplitude damping (SGAD) channel is a quantum channel that models a general noise process incorporating the effects of bath squeezing, dissipation, and decoherence. In this paper, we analyze the dynamics of quantum entanglement and discord in the SGAD channel with memory.
