Phys. Rev. A 67, 022320 (2003) [5 pages]Characterizing the entanglement of bipartite quantum systemsReceived 24 October 2002; published 28 February 2003 We derive a separability criterion for bipartite quantum systems which generalizes the already known criteria. It is based on observables having generic commutation relations. We then discuss in detail the relation among these criteria. © 2003 The American Physical Society URL:
