Entanglement dynamics of two independent qubits in environments with and without memory
TLDR
In this paper, the authors analyzed the dynamics of two-qubit entanglement, when the two qubits are initially in a mixed extended Werner-like state and each of them is in a zero temperature non-Markovian environment.Abstract:
Here is analyzed the dynamics of two-qubit entanglement, when the two qubits are initially in a mixed extended Werner-like state and each of them is in a zero temperature non-Markovian environment. The dependence of entanglement dynamics on the purity and degree of entanglement of the initial states and on the amount of non-Markovianity is also given. This extends the previous work about non-Markovian effects on the two-qubit entanglement dynamics for initial Bell-like states [Bellomo et al., Phys. Rev. Lett. 99, 160502 (2007)]. The effect on the two-qubit entanglement dynamics of nonzero temperature in Markovian environments is finally studied.read more

Open-System Dynamics of Entanglement
TL;DR: In this paper, the authors present an overview of recent theoretical and experimental efforts to underpin the dynamics of entanglement in open quantum systems and survey how it evolves due to the interaction of the entangled system with its surroundings.

Dynamics of quantum correlations in two-qubit systems within non-markovian environments
TL;DR: In this paper, the authors review some of the most recent results on the dynamics of correlations in bipartite systems embedded in non-Markovian environments and briefly discuss the occurrence of revivals of quantum correlations in classical environments.

Open-system dynamics of entanglement:a key issues review
TL;DR: An overview of recent theoretical and experimental efforts to underpin the dynamics of entanglement under the influence of noise is presented, and how it evolves due to the unavoidable interaction of the entangled system with its surroundings is surveyed.
Journal ArticleDOI
Experimental demonstration of photonic entanglement collapse and revival.
TL;DR: It is shown that entanglement can be revived even after it suffers from sudden death, and a maximally revived state is shown to violate a Bell's inequality with 4.1 standard deviations which verifies its quantum nature.

On the Einstein-Podolsky-Rosen paradox
TL;DR: In this article, it was shown that even without such a separability or locality requirement, no hidden variable interpretation of quantum mechanics is possible and that such an interpretation has a grossly nonlocal structure, which is characteristic of any such theory which reproduces exactly the quantum mechanical predictions.
