# Design and experimental performance of local entanglement witness operators

@article{Amaro2020DesignAE, title={Design and experimental performance of local entanglement witness operators}, author={David Amaro and Markus P. M{\"u}ller}, journal={Physical Review A}, year={2020} }

Entanglement is a central concept in quantum information and a key resource for many quantum protocols. In this work we propose and analyze a class of entanglement witnesses that detect the presence of entanglement in subsystems of experimental multi-qubit stabilizer states. The witnesses we propose can be decomposed into sums of Pauli operators and can be efficiently evaluated by either two measurement settings only or at most a number of measurements that only depends on the size of the…

The theory of MDI-EW is extended to remove the necessity of prior knowledge about the two-qubit states to be witnessed and the robustness of this approach against noise is demonstrated by witnessing entanglement down to an entangled state fraction close to 0.4.

All these tests—based on the very same data—give rise to quantitative estimates in terms of entanglement measures, and if a test is strongly violated, one can also infer that the state was quantitatively very much entangled, in the bipartite and multipartite setting.
