• Abstract: It is an interesting problem to construct genuine tripartite entangled states based on the collective use of two bipartite entangled states. We consider the case that the states are two-qubit Werner states, we construct the interval of parameter of Werner states such that the tripartite state is genuine entangled. Further, we present the way of detecting the tripartite genuine entanglement using current techniques in experiments. We also investigate the lower bound of genuine multipartite entanglement concurrence.

  We study the exotic Landau problem at the classical level where two conserved quantities are derived. We form entangled coherent states which are Bell-like states labeled quasi-Bell states. The effect of non-maximality of a quasi-Bell state based quantum channel is investigated in the context of a teleportation of a qubit.

• Entanglement and fermionization of two distinguishable fermions in a strict and non strict one-dimensional space [0.0]
  We present two alternative representations of the ground state that we associate with two different types of one-dimensional spaces. We find that the entanglement of the ground state is strongly conditioned by those one-dimensional space features. In the strongly repulsive regime the ground state changes smoothly from a superposition of Slater-like states to a finite superposition of Slaters.

• Constraint relation between steerability and concurrence for two-qubit states [6.687934752525343]
  Entanglement and steering are used to describe quantum inseparabilities. A natural question arises concerning how much territory steerability occupies entanglement for a general two-qubit entangled state. We investigate the constraint relation between steerability and concurrence by using two kinds of evolutionary states and randomly generated two-qubit states.
