Quantum entanglement in the triangle network
Tristan Kraft, Sébastien Designolle, Christina Ritz +3
Beyond future applications, quantum networks open interesting fundamental perspectives, notably novel forms of quantum correlations. In this work we discuss quantum correlations in…
Characterizing multipartite entanglement classes via higher-dimensional embeddings
Christina Ritz, Cornelia Spee, Otfried Gühne
Witness operators are a central tool to detect entanglement or to distinguish among the different entanglement classes of multiparticle systems, which can be defined using stochast…
Characterizing Genuine Multilevel Entanglement
Tristan Kraft, Christina Ritz, Nicolas Brunner +2
Entanglement of high-dimensional quantum systems has become increasingly important for quantum communication and experimental tests of nonlocality. However, many effects of high-di…
Qudit Hypergraph States
Frank E. S. Steinhoff, Christina Ritz, Nikolai Miklin +1
We generalize the class of hypergraph states to multipartite systems of qudits, by means of constructions based on the d-dimensional Pauli group and its normalizer. For simple hype…
