Characterization and properties of weakly optimal entanglement witnesses

Bang-Hai Wang, Hai-Ru Xu, Steve Campbell +1

We present an analysis of the properties and characteristics of weakly optimal entanglement witnesses, that is witnesses whose expectation value vanishes on at least one product ve…

Universal methods for extending any entanglement witness from the bipartite to the multipartite case

Bang-Hai Wang, Hai-Ru Xu, Simone Severini

Any bipartite entanglement witness $W$ can be written as $W = c_{σ} I - σ$ , where $σ$ is a quantum state, $I$ is the identity matrix, and $c_{σ}$ is a non-negative number. We present a gene…
