Quantum discord in nuclear magnetic resonance systems at room temperature
J. Maziero, R. Auccaise, L. C. Celeri +6
We review the theoretical and the experimental aspects regarding the quantification and identification of quantum correlations in liquid-state nuclear magnetic resonance (NMR) syst…
On the quantumness of correlations in nuclear magnetic resonance
D. O. Soares-Pinto, R. Auccaise, J. Maziero +3
Nuclear Magnetic Resonance (NMR) was successfully employed to test several protocols and ideas in Quantum Information Science. In most of these implementations the existence of ent…
Experimental analysis of the quantum complementarity principle
R. Auccaise, R. M. Serra, J. G. Filgueiras +3
One of the milestones of quantum mechanics is Bohr's complementarity principle. It states that a single quantum can exhibit a particle-like \emph{or} a wave-like behaviour, but nev…
Long-range quantum discord in critical spin systems
J. Maziero, L. C. Céleri, R. M. Serra +1
We show that quantum correlations as quantified by quantum discord can characterize quantum phase transitions by exhibiting nontrivial long-range decay as a function of distance in…
Symmetry aspects of quantum discord
J. Maziero, L. C. Celeri, R. M. Serra
Quantum discord (QD) reveals the nonclassical nature of correlations in bipartite quantum states, going beyond the entanglement-separability paradigm. In this article we discuss th…
Nonclassical correlation in NMR quadrupolar systems
D. O. Soares-Pinto, L. C. Celeri, R. Auccaise +5
The existence of quantum correlation (as revealed by quantum discord), other than entanglement and its role in quantum-information processing (QIP), is a current subject for discus…
