    "abstract": "We show that all quantum states that do not have a positive partial transpose\nare distillable via channels, which preserve the positivity of the partial\ntranspose. The question whether NPT bound entanglement exist is therefore\nclosely related to the connection between the set of separable superoperators\nand PPT-preserving maps.",
