Phys. Rev. A 80, 042314 (2009) [5 pages]Spectral conditions for entanglement witnesses versus bound entanglementReceived 20 August 2009; published 19 October 2009 It is shown that entanglement witnesses constructed via the family of spectral conditions are decomposable, i.e., cannot be used to detect bound entanglement. It supports several observations that bound entanglement reveals highly nonspectral features. © 2009 The American Physical Society URL:
