Generalized qudit choi maps

Following the linear programming prescription of Jafarizadeh [Phys. Rev. A 72, 062106 (2005)], the d circle times 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 circle times d Bell diagonal separable states and constructing corresponding bound entangled states, it is shown that the obtained d circle times d Bell states diagonal entanglement witnesses (consequently qudit Choi maps) are nondecomposable in a certain range of their parameters.
