Abstract
Recently, a computational criterion of separability induced by the greatest cross norm was proposed by Rudolph (2002 Preprint quant-ph/0202121). There, Rudolph conjectured that the new criterion is neither weaker nor stronger than the positive partial-transpose criterion for separability. We show that there exists a counterexample to the this claim, that is, the proposed criterion is not equivalent to the positive partial-transpose criterion.
