  • Entanglement and Nonlocality are Inequivalent for Any Number of Parties 

    Augusiak, R.; Demianowicz, M.; Tura, J.; Acín, Antonio (APS, 2015-07-15)
    Article
    Open Access
    Understanding the relation between nonlocality and entanglement is one of the fundamental problems in quantum physics. In the bipartite case, it is known that these two phenomena are inequivalent, as there exist entangled ...
  • Nonlocality in many-body quantum systems detected with two-body correlators 

    Tura, J.; Augusiak, Remigiusz; Sainz, A. B.; Lücke, B.; Klempt, C.; Lewenstein, Maciej; Acin, Antonio (Science Direct, 2015-07-30)
    Article
    Open Access
    Contemporary understanding of correlations in quantum many-body systems and in quantum phase transitions is based to a large extent on the recent intensive studies of entanglement in many-body systems. In contrast, much ...
