DUCUARA, Andrés Felipe; MADRONERO, Javier  and  REINA, John Henry. On the Activation of Quantum Nonlocality. Univ. Sci. [online]. 2016, vol.21, n.2, pp.129-158. ISSN 0122-7483.  https://doi.org/10.11144/javeriana.SC21-2.otao.

We report on some quantum properties of physical systems, namely, entanglement, nonlocality, k-copy nonlocality (superactivation of nonlocality), hidden nonlocality (activation of nonlocality through local filtering) and the activation of nonlocality through tensoring and local filtering. The aim of this work is two-fold. First, we provide a review of the numerical procedures that must be followed in order to calculate the aforementioned properties, in particular, for any two-qubit system, and reproduce the bounds for two-qudit Werner states. Second, we use such numerical tools to calculate new bounds of these properties for two-qudit Isotropic states and two-qubit Hirsch states.

Keywords : Qubits; quantum information; quantum nonlocality; entanglement.
