Simplifying Schmidt number witnesses via higher-dimensional embeddings
Florian Hulpke, Dagmar Bruss, Maciej Lewenstein +1
We apply the generalised concept of witness operators to arbitrary convex sets, and review the criteria for the optimisation of these general witnesses. We then define an embedding…

Entanglement properties of composite quantum systems
K. Eckert, O. Gühne, F. Hulpke +6
We present here an overview of our work concerning entanglement properties of composite quantum systems. The characterization of entanglement, i.e. the possibility to assert if a g…
