Proving the Generation of Genuine Multipartite Entanglement in a Single-Neutron Interferometer Experiment
Daniel Erdösi, Marcus Huber, Beatrix C. Hiesmayr +1
We present experimental evidence of the generation of distinct types of genuine multipartite entanglement between three degrees of freedom, two internal and one external degree of…
Quantum Hypergraph States
M. Rossi, M. Huber, D. Bruß +1
We introduce a class of multiqubit quantum states which generalizes graph states. These states correspond to an underlying mathematical hypergraph, i.e. a graph where edges connect…
The structure of multidimensional entanglement in multipartite systems
Marcus Huber, Julio I. de Vicente
We explore the structure of multipartite quantum systems which are entangled in multiple degrees of freedom. We find necessary and sufficient conditions for the characterization of…
Genuinely Multipartite Concurrence of N-qubit X-matrices
S. M. Hashemi Rafsanjani, M. Huber, C. J. Broadbent +1
We find an algebraic formula for the N-partite concurrence of N qubits in an X-matrix. X- matricies are density matrices whose only non-zero elements are diagonal or anti-diagonal…
Quantum gates and multipartite entanglement resonances realized by non-uniform cavity motion
Nicolai Friis, Marcus Huber, Ivette Fuentes +1
We demonstrate the presence of genuine multipartite entanglement between the modes of quantum fields in non-uniformly moving cavities. The transformations generated by the cavity m…
Determining lower bounds on a measure of multipartite entanglement from few local observables
Jun-Yi Wu, Hermann Kampermann, Dagmar Bruß +2
We introduce a method to lower bound an entropy-based measure of genuine multipartite entanglement via nonlinear entanglement witnesses. We show that some of these bounds are tight…
