It includes original results as well as detailed methods and explanations for a number of different threads of research: positive partial transpose (PPT) entanglement in the symmetric states; a novel, experimentally friendly method to detect nonlocal correlations in many-body systems; the non-equivalence between entanglement and nonlocality; and elemental monogamies of correlations. Entanglement and nonlocal correlations constitute two fundamental resources for quantum information processing, as they allow novel tasks that are otherwise impossible in a classical scenario. However, their elusive characterization is still a central problem in quantum information theory. The main reason why such a fundamental issue remains a formidable challenge lies in the exponential growth in complexity of the Hilbert space as well as the space of multipartite correlations. Physical systems of interest, on the other hand, display symmetries that can be exploited to reduce this complexity, opening the possibility that some of these questions become tractable for such systems.Springer Theses, Recognizing Outstanding Ph.D. Research,2190-5053Quantum physicsMathematical physicsPhase transformations (Statistical physics)Condensed materialsQuantum computersSpintronicsQuantum Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/P19080Mathematical Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/M35000Quantum Gases and Condensateshttps://scigraph.springernature.com/ontologies/product-market-codes/P24033Quantum Information Technology, Spintronicshttps://scigraph.springernature.com/ontologies/product-market-codes/P31070Quantum physics.Mathematical physics.Phase transformations (Statistical physics).Condensed materials.Quantum computers.Spintronics.Quantum Physics.Mathematical Physics.Quantum Gases and Condensates.Quantum Information Technology, Spintronics.530.12Tura i Brugués Jordiauthttp://id.loc.gov/vocabulary/relators/aut818790MiAaPQMiAaPQMiAaPQBOOK9910155273303321Characterizing Entanglement and Quantum Correlations Constrained by Symmetry1825350UNINA
