Dynamics of non-Markovian open quantum systems

I De Vega, D Alonso - Reviews of Modern Physics, 2017 - APS
Open quantum systems (OQSs) cannot always be described with the Markov approximation,
which requires a large separation of system and environment time scales. An overview is …

Open-system dynamics of entanglement: a key issues review

L Aolita, F De Melo, L Davidovich - Reports on Progress in …, 2015 - iopscience.iop.org
One of the greatest challenges in the fields of quantum information processing and quantum
technologies is the detailed coherent control over each and every constituent of quantum …

Dynamics of quantum correlations in two-qubit systems within non-Markovian environments

RL Franco, B Bellomo, S Maniscalco… - International Journal of …, 2013 - World Scientific
Knowledge of the dynamical behavior of correlations with no classical counterpart, like
entanglement, nonlocal correlations and quantum discord, in open quantum systems is of …

Non-Markovian effect on the quantum discord

B Wang, ZY Xu, ZQ Chen, M Feng - … Review A—Atomic, Molecular, and Optical …, 2010 - APS
We study the non-Markovian effect on the dynamics of the quantum discord by exactly
solving a model consisting of two independent qubits subject to two zero-temperature non …

Cavity-based architecture to preserve quantum coherence and entanglement

ZX Man, YJ Xia, R Lo Franco - Scientific reports, 2015 - nature.com
Quantum technology relies on the utilization of resources, like quantum coherence and
entanglement, which allow quantum information and computation processing. This …

Entanglement trapping in structured environments

B Bellomo, R Lo Franco, S Maniscalco… - Physical Review A …, 2008 - APS
We highlight the direct link between the time-dependent entanglement and single-qubit
excited-state population for two independent qubits, each coupled to a zero-temperature …

Revival of quantum correlations without system-environment back-action

R Lo Franco, B Bellomo, E Andersson… - Physical Review A …, 2012 - APS
Revivals of quantum correlations have often been explained in terms of back-action on
quantum systems by their quantum environment (s). Here we consider a system of two …

Experimental demonstration of photonic entanglement collapse and revival

JS Xu, CF Li, M Gong, XB Zou, CH Shi, G Chen… - Physical review …, 2010 - APS
We demonstrate the collapse and revival features of the entanglement dynamics of different
polarization-entangled photon states in a non-Markovian environment. Using an all-optical …

Quantum-memory-assisted entropic uncertainty principle, teleportation, and entanglement witness in structured reservoirs

ML Hu, H Fan - Physical Review A—Atomic, Molecular, and Optical …, 2012 - APS
We relate the principle of quantum-memory-assisted entropic uncertainty to quantum
teleportation and show geometrically that any two-qubit state which lowers the upper bound …

Mechanism of entanglement preservation

QJ Tong, JH An, HG Luo, CH Oh - Physical Review A—Atomic, Molecular, and …, 2010 - APS
We study the entanglement preservation of two qubits locally interacting with their reservoirs.
We show that the existence of a bound state of the qubit and its reservoir and the non …
