dc.descriptionWe study generalized concurrences as a tool to detect the entanglement of bipartite quantum systems. By considering the case of 2 X 4 states of rank 2, we prove that generalized concurrences do not, in general, give a necessary and sufficient condition of separability. We identify a set of entangled states which are undetected by this method.
dc.descriptionIt replaces two previous versions. The new version incorporates important references on the topic. It corrects a mistake. Title has changed
