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…
Environment-induced sudden transition in quantum discord dynamics
R. Auccaise, L. C. Celeri, D. O. Soares-Pinto +7
Non-classical correlations play a crucial role in the development of quantum information science. The recent discovery that non-classical correlations can be present even in separa…
Experimentally Witnessing the Quantumness of Correlations
R. Auccaise, J. Maziero, L. C. Celeri +6
The quantification of quantum correlations (other than entanglement) usually entails laboured numerical optimization procedures also demanding quantum state tomographic methods. Th…
Equivalence between Redfield and master equation approaches for a time-dependent quantum system and coherence control
D. O. Soares-Pinto, M. H. Y. Moussa, J. Maziero +4
We present a derivation of the Redfield formalism for treating the dissipative dynamics of a time-dependent quantum system coupled to a classical environment. We compare such a for…
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…
