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. 410 0$aSpringer Theses, Recognizing Outstanding Ph.D. Research,$x2190-5053 606 $aQuantum physics 606 $aMathematical physics 606 $aPhase transformations (Statistical physics) 606 $aCondensed materials 606 $aQuantum computers 606 $aSpintronics 606 $aQuantum Physics$3https://scigraph.springernature.com/ontologies/product-market-codes/P19080 606 $aMathematical Physics$3https://scigraph.springernature.com/ontologies/product-market-codes/M35000 606 $aQuantum Gases and Condensates$3https://scigraph.springernature.com/ontologies/product-market-codes/P24033 606 $aQuantum Information Technology, Spintronics$3https://scigraph.springernature.com/ontologies/product-market-codes/P31070 615 0$aQuantum physics. 615 0$aMathematical physics. 615 0$aPhase transformations (Statistical physics). 615 0$aCondensed materials. 615 0$aQuantum computers. 615 0$aSpintronics. 615 14$aQuantum Physics. 615 24$aMathematical Physics. 615 24$aQuantum Gases and Condensates. 615 24$aQuantum Information Technology, Spintronics. 676 $a530.12 700 $aTura i Brugués$b Jordi$4aut$4http://id.loc.gov/vocabulary/relators/aut$0818790 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910155273303321 996 $aCharacterizing Entanglement and Quantum Correlations Constrained by Symmetry$91825350 997 $aUNINA
