  • Elemental and tight monogamy relations in nonsignaling theories 

    Augusiak, Remigiusz; Demianowicz, Maciej; Pawłowski, M.; Tura, Jordi; Antonio, Acín Dal Maschio (American Physical Society, 2014-11-17)
    Article
    Open Access
    Physical principles constrain the way nonlocal correlations can be distributed among distant parties. These constraints are usually expressed by monogamy relations that bound the amount of Bell inequality violation observed ...
  • Inequivalence of entanglement, steering, and Bell nonlocality for general measurements 

    Quintino, Marco Tulio; Vértesi, Tamas; Cavalcanti, Daniel; Augusiak, Remigiusz; Demianowicz, Maciej; Acín, Antonio; Brunner, Nicolas (APS, 2015-09-08)
    Article
    Open Access
    Einstein-Podolsky-Rosen steering is a form of inseparability in quantum theory commonly acknowledged to be intermediate between entanglement and Bell nonlocality. However, this statement has so far only been proven for a ...
  • 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 ...
  • Progress towards a unified approach to entanglement distribution 

    Streltsov, Alexander; Augusiak, Remigiusz; Demianowicz, Maciej; Lewenstein, Maciej (APS, 2015-07-30)
    Article
    Open Access
    Entanglement distribution is key to the success of secure communication schemes based on quantum mechanics, and there is a strong need for an ultimate architecture able to overcome the limitations of recent proposals such ...
