چکیده
Following the linear programming prescription of Ref. [6], the d ⊗ d Bell diagonal entanglement witnesses are provided. By using Jamiolkowski isomorphism, it is shown that the corresponding positive maps are the generalized qudit Choi maps. Also by manipulating particular d ⊗ d Bell diagonal separable states and constructing corresponding bound entangled states, it is shown that thus obtained d ⊗ d BDEW's (consequently qu-dit Choi maps) are non-decomposable in certain range of their parameters.

We calculate the entanglement between two spins in the ferromagnetic Heisen-berg chain at low temperatures, and show that when only the ground state and the one particle states are populated, the entanglement profile is a gaussian with a characteristic length depending on the temperature and the coupling between spins. The magnetic field only affects the amplitude of the profile and not its cha...
