Abstract

We study the stability of NPT property of an arbitrary pure entangled state under the mixture of arbitrary pure separable states. For bipartite pure states with Schmidt number n (n>1) which is NPT, we show that this state is still NPT when it is mixed with no more than frac{n(n-1)}{2}-1 arbitrary pure separable states. This result is generalized to multipartite case.
