A simple class of bound entangled states based on the properties of the antisymmetric subspace

We provide simple analytical and numerical examples of entangled states that are positive under partial transposition, and hence undistillable. The construction makes use of the properties of the projectors onto the symmetric and antisymmetric subspaces, and the examples can be considered as generalizations of the celebrated Werner states.
