Simple class of bound entangled states based on the properties of the antisymmetric subspace
Enrico Sindici, Marco Piani · Physical Review A · 2018
A recipe to construct bound entangled states, i.e., entangled in a way that cannot be distilled, is presented. Contrary to known previous examples, the proposed method leads to states with a simpler structure, considered as generalizations of the well-known $W$ states, which may, therefore, be more attractive for experimental investigations.
