Remarks on the Cross Norm Criterion for Separability
S. J. Akhtarshenas, M. A. Jafarizadeh
abstract: Recently in Reference [ quant-ph/0202121] a computational criterion of
separability induced by greatest cross norm is proposed by Rudolph. There,
Rudolph conjectured that the new criterion is not weaker than positive partial
transpose criterion for separability. We show that there exist counterexample
to this claim, that is, proposed criterion is weaker than the positive partial
transpose criterion.
