We provide a more sophisticated proof, since we could not overcome the criticism that the used angles are not angles between v

Scientific paper

Bound entanglement with a nonpositive partial transposition (NPT) does not
exist. For any NPT entangled state a distillation procedure can be based on a
certain number of copies. This number is the minimal Schmidt rank of a pure
state needed to witness the NPT entanglement under study.
