Experimental investigation of classical and quantum correlations under decoherence
It is well known that many operations in quantum information processing depend largely on
a special kind of quantum correlation, that is, entanglement. However, there are also …

Classical and quantum correlations under decoherence
Recently some authors have pointed out that there exist nonclassical correlations which are
more general, and possibly more fundamental, than entanglement. For these general …

Behavior of quantum correlations under local noise
A Streltsov, H Kampermann, D Bruß - Physical review letters, 2011 - APS
We characterize the behavior of quantum correlations under the influence of local noisy
channels. Intuition suggests that such noise should be detrimental for quantumness. When …

Experimental recovery of quantum correlations in absence of system-environment back-action
Revivals of quantum correlations in composite open quantum systems are a useful
dynamical feature against detrimental effects of the environment. Their occurrence is …

Quantum coherence of multiqubit states in correlated noisy channels
The long-time maintenance of quantum coherence is crucial for its practical applications. We
explore decoherence process of a multiqubit system passing through a correlated channel …

Frozen quantum coherence
TR Bromley, M Cianciaruso, G Adesso - Physical review letters, 2015 - APS
We analyze under which dynamical conditions the coherence of an open quantum system is
totally unaffected by noise. For a single qubit, specific measures of coherence are found to …

Theoretical and experimental aspects of quantum discord and related measures
Correlations are a very important tool in the study of multipartite systems, for both classical
and quantum ones. The discussion about the quantum nature of correlations permeates …

Sudden transition between classical and quantum decoherence
L Mazzola, J Piilo, S Maniscalco - Physical review letters, 2010 - APS
We study the dynamics of quantum and classical correlations in the presence of
nondissipative decoherence. We discover a class of initial states for which the quantum …
