Abstract

The problem of a proper gap between positive partial transpose (PPT) states and distillable states under this "PPT-preserving" protocol was studied. It was found that the gap disappears when a strong protocol is allowed. As a result, it was not possible to obtain a conclusive evidence about the gap for weaker protocols.
