Описание: Challenges the long-held "two-tier" idea of religion that separated the religious practices of the sophisticated elites from those of the superstitious masses, instead arguing that the cult of the saints crossed boundaries and played a dynamic part in both the Christian faith and the larger world of late antiquity.
Описание: This thesis focuses on the study and characterization of entanglement and nonlocal correlations constrained under symmetries. 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.
Описание: Represents the proceedings of the interdisciplinary stream of the international workshop (Part 1) Times of Entanglement, 21 - 22 September 2010 at the Minsheng Art Museum in Shanghai, People`s Republic of China.
Описание: A collection of lecture notes/contributions from a summer school on decoherence, entanglement & entropy and a workshop on MPS (matrix product states) & DMRG (density matrix renormalization group). It is prepared in a self-contained manner so that readers with a modest background in quantum information and quantum computing may understand.
