Witness to detect quantum correlation of bipartite states in arbitrary dimension

Quantum Physics 2011-04-05 v1

Abstract

In this work we introduce a nonlinear witness that is a sufficient condition for detecting the vanishment of quantum correlation of bipartite states. Our result directly generalizes the result of [J. Maziero, R. M. Serra, arXiv:1012.3075] to arbitrary dimension based on the Bloch representation of density matrices.
