In 1999, Asher Peres conjectured that bound entanglement can never lead to Bell nonlocality. Recently this conjecture has been proven to be false, by identifying a 3×3 bound entangled state that violates a bipartite Bell inequality [1]. In this talk, we discuss implications of this result to the relation between different facets of quantum entanglement. Also, possible extensions of the problem to higher dimensional and multipartite states are presented.
