    • Problem of quantifying quantum correlations with non-commutative discord 

      Majtey, Ana Paula; Bussandri, Diego Gastón; Osán, Tristán Martín; Lamberti, Pedro Walter; Valdés-Hernández, Andrea (2017)
      In this work we analyze a non-commutativity measure of quantum correlations recently proposed by Y. Guo [Sci. Rep. 6, 25241 (2016)]. By resorting to a systematic survey of a two-qubit system, we detected an undesirable ...
    • Unified framework to determine Gaussian states in continuous-variable systems 

      Nicacio, Fernando; Valdés-Hernández, Andrea; Majtey, Ana Paula; Toscano, Fabricio (2017)
      Gaussian states are the backbone of quantum information protocols with continuous-variable systems whose power relies fundamentally on the entanglement between the different modes. In the case of global pure states, knowledge ...
