Emaranhamento em sistemas de partículas indistinguíveis
(Universidade Federal de Minas GeraisUFMG, 2011-08-23)
In this work we studied the issue of quantification of entanglement in quantum systems performing a detailed analysis since its fundamental principles, i.e, the postulates of the theory of entanglement measures, and thus ...
Entanglement temperature in molecular magnets composed of S-spin dimers
(EPL ASSOCIATION, EUROPEAN PHYSICAL SOCIETY, 2009)
In the present work, we investigate the quantum thermal entanglement in molecular magnets composed of dimers of spin S, using an Entanglement Witness built from measurements of magnetic susceptibility. An entanglement ...
Sistemas de pocos cuerpos en un entorno del umbral del continuo :
(2010)
En esta tesis se presenta un estudio de varios sistemas cuánticos cuyo común denominador es que poseen uno o más estados ligados cerca del umbral de energía del continuo. En este aspecto se analizaron los diagramas de ...
Dicke states: production from EPR pairs and entanglement analysis
(Universidade Federal de PernambucoUFPEBrasilPrograma de Pos Graduacao em Fisica, 2018)
High-dimensional angular two-photon interference and angular qudit states
(The Optical Society, 2020-06)
Using angular position–orbital angular momentum entangled photons, we propose an experiment to generate maximally entangled states in D-dimensional quantum systems, the so called qudits, by exploiting correlations of ...
Experimentally Witnessing the Quantumness of Correlations
(AMER PHYSICAL SOC, 2011)
The quantification of quantum correlations (other than entanglement) usually entails labored numerical optimization procedures also demanding quantum state tomographic methods. Thus it is interesting to have a laboratory ...
Quantumness of correlations in finite dimensional systems
(Universidade Federal de Minas GeraisUFMG, 2014-04-11)
Some phenomena are exclusive of quantum systems, in other words, there no exist counterpart in classical mechanics. Two examples extensively discussed in recent years are the quantum entanglement and quantum non locality, ...
Entanglement, coherence and correlation in atomic and molecular systems
(Grupo de Física Atómica y MolecularMedellín, Colombia, 2022)
