On the Correlations Between Quantum Entanglement and q-Information
Measures
J. Batle, M. Casas, A. Plastino, A. R. Plastino
abstract: In the present study we revisit the application of the $q$-information
measures $R_q$ of R\'enyi's and $S_q$ of Tsallis' to the discussion of special
features of two qubits systems. More specifically, we study the correlations
between the $q$-information measures and the entanglement of formation of a
general (pure or mixed) state $\rho$ describing a system of two qubits. The
analysis uses a Monte Carlo procedure involving the 15-dimensional 2-qubits
space of pure and mixed states, under the assumption that these states are
uniformly distributed according to the product measure recently introduced by
Zyczkowski {\it et al} [Phys. Rev. A {\bf 58} (1998) 883].
