Revealing entanglement through local features of phase-space distributions
Elena Callus, Martin Gärttner, Tobias Haas
We formulate an infinite hierarchy of continuous-variable separability criteria in terms of quasiprobability distributions and their derivatives evaluated at individual points in p…

Interferometric detection of continuous-variable entanglement using two states
Elena Callus, Martin Gärttner, Tobias Haas
The efficient witnessing and certification of entanglement is necessitated by its ubiquitous use in various aspects of quantum technologies. In the case of continuous-variable bipa…
