    • Detection of nonlocality with two-body correlation functions 

      Aloy López, Albert (Universitat Politècnica de Catalunya, 2015-09-10)
      Projecte Final de Màster Oficial
      Accés obert
      Nonlocality detection in multipartite quantum systems is of great interest. The most popular tool to detect nonlocality in quantum systems are Bell inequalities. Most of the provided constructions of multipartite Bell ...

    • Exploring nonlocal correlations in many-body systems 

      López Pastor, Víctor José (Universitat Politècnica de Catalunya, 2018-07-19)
      Projecte Final de Màster Oficial
      Accés obert
      We address the question of how to evaluate the Bell correlations depth, i.e. the number of parties sharing genuinely nonlocal correlations in a multipartite system. Previous work has shown that it is possible to construct ...

    • Secrecy in Prepare-and-Measure Clauser-Horne-Shimony-Holt Tests with a Qubit Bound 

      Woodhead, Erik; Pironio, Stefano (APS, 2015-10-06)
      Article
      Accés obert
      The security of device-independent (DI) quantum key distribution (QKD) protocols relies on the violation of Bell inequalities. As such, their security can be established based on minimal assumptions about the devices, but ...
