We use some general results regarding positive maps to exhibit examples of non-decomposable maps and 2 ×2N , N ≥ 2, bound entangled states, e.g. non distillable bipartite states of N+N qubits.

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...

In this paper, we construct a measure of entanglement by generalizing the quadric polynomial of the Segre variety for general multipartite states. We give explicit expressions for general pure three-partite and four-partite states. Moreover, we will discuss and compare this measure of entanglement with the generalized concurrence.
