In the present study we revisit the application of the q-information measures R q of Rényi'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 ρ describing a system of two qubits. The analysis uses a Monte Carlo proce...

The newly developed iterative method based on Green function defined by quadratures along a single trajectory is combined with the variational method to solve the ground state quantum wave function for central potentials. As an example , the method is applied to discuss the ground state solution of Yukawa potential, using Hulthen solution as the trial function.

Distillable entanglement (E d) is one of the acceptable measures of entanglement of mixed states. Based on discrimination through local operation and classical communication, this paper gives E d for two classes of orthogonal multipartite maximally entangled states.
