Phys. Rev. A 70, 022322 (2004) [5 pages]Measures of entanglement in multipartite bound entangled states
Tzu-Chieh Wei1, Joseph B. Altepeter1, Paul M. Goldbart1, and William J. Munro2 Received 13 September 2003; published 27 August 2004 Bound entangled states are states that are entangled but from which no entanglement can be distilled if all parties are allowed only local operations and classical communication. However, in creating these states one needs nonzero entanglement resources to start with. Here, the entanglement of two distinct multipartite bound entangled states is determined analytically in terms of a geometric measure of entanglement and a related quantity. The results are compared with those for the negativity and the relative entropy of entanglement. ©2004 The American Physical Society
