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…
Measuring bipartite quantum correlations of an unknown state
I. A. Silva, D. Girolami, R. Auccaise +6
We report the experimental measurement of bipartite quantum correlations of an unknown two-qubit state. Using a liquid state Nuclear Magnetic Resonance (NMR) setup and employing ge…
Evidence for entanglement at high temperatures in an engineered molecular magnet
M. S. Reis, S. Soriano, A. M. dos Santos +3
The molecular compound [Fe(-oxo)(CHN)(CO)] was designed and synthesized for the first time and its structure was determined u…
Towards higher precision and operational use of optical homodyne tomograms
M. Bellini, A. S. Coelho, S. N. Filippov +2
We present the results of an operational use of experimentally measured optical tomograms to determine state characteristics (purity) avoiding any reconstruction of quasiprobabilit…
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…
