Measures of entanglement in multipartite bound entangled states
Tzu-Chieh Wei, Joseph B. Altepeter, Paul M. Goldbart, William J. Munro
abstract: 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.
