The two-qubit amplitude damping channel: Characterization using quantum stabilizer codes [PDF]
Annals of Physics, 2015 A protocol based on quantum error correction based characterization of quantum dynamics (QECCD) is developed for quantum process tomography on a two-qubit system interacting dissipatively with a vacuum bath. The method uses a 5-qubit quantum error correcting code that corrects arbitrary errors on the first two qubits, and also saturates the quantum ...

Reliable Channel-Adapted Error Correction: Bacon-Shor Code Recovery from Amplitude Damping. [PDF]
Physical Review Letters, 2017 We construct two simple error correction schemes adapted to amplitude damping noise for Bacon-Shor codes and investigate their prospects for fault-tolerant implementation.

Time-correlated quantum amplitude-damping channel [PDF]
Physical Review A, 2003 We analyze the problem of sending classical information through qubit channels where successive uses of the channel are correlated. This work extends the analysis of C. Macchiavello and G. M. Palma to the case of a non-Pauli channel - the amplitude damping channel. Using the channel description outlined in S.

Protecting entanglement from correlated amplitude damping channel using weak measurement and quantum measurement reversal [PDF]
Quantum Information Processing, 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.

Quantum capacity of an amplitude-damping channel with memory [PDF]
Quantum Information Processing, 2014 We calculate the quantum capacity of an amplitude-damping channel with time-correlated Markov noise, for two channel uses. Our results show that memory of the channel increases its ability to transmit quantum information significantly.

Information transmission over an amplitude damping channel with an arbitrary degree of memory [PDF]
, 2015 We study the performance of a partially correlated amplitude damping channel acting on two qubits. We derive lower bounds for the single-shot classical capacity by studying two kinds of quantum ensembles, one which allows to maximize the Holevo quantity ...

Intraparticle entanglement in noisy quantum channels: degradation and revival through amplitude damping [PDF]
Frontiers in Quantum Science and TechnologyQuantum correlations between two or more different degrees of freedom of the same particle are sometimes referred to as intraparticle entanglement. In this work, we study these intraparticle correlations between two different degrees of freedom under ...

Discriminating qubit amplitude damping channels [PDF]
Journal of Physics A: Mathematical and Theoretical, 2021 Abstract We address the issue of the discrimination between two-qubit amplitude damping channels by exploring several strategies. For the single-shot, we show that the excited state does not always give the optimal input, and that side entanglement assistance has limited benefit.
