Realism and single-quanta nonlocality

G. S. Paraoanu

We show that local realism applied to states characterized by a single quanta equally and coherently shared between a number of qubits (so-called W states) produces predictions inc…

Taming multiparticle entanglement

Bastian Jungnitsch, Tobias Moroder, Otfried Gühne

We present an approach to characterize genuine multiparticle entanglement using appropriate approximations in the space of quantum states. This leads to a criterion for entanglemen…

14-qubit entanglement: creation and coherence

Thomas Monz, Philipp Schindler, Julio T. Barreiro +7

We report the creation of Greenberger-Horne-Zeilinger states with up to 14 qubits. By investigating the coherence of up to 8 ions over time, we observe a decay proportional to the…

Entanglement criteria and full separability of multi-qubit quantum states

Otfried Gühne

We introduce an entanglement criterion to exclude full separability of quantum states. We present numerical evidence that the criterion is necessary and sufficient for the class of…

Direct generation of photon triplets using cascaded photon-pair sources

H. Hübel, D. R. Hamel, A. Fedrizzi +3

Non-classical states of light, such as entangled photon pairs and number states, are essential for fundamental tests of quantum mechanics and optical quantum technologies. The most…

Feasibility of 300 km Quantum Key Distribution with Entangled States

Thomas Scheidl, Rupert Ursin, Alessandro Fedrizzi +8

A significant limitation of practical quantum key distribution (QKD) setups is currently their limited operational range. It has recently been emphasized (X. Ma, C.-H. F. Fung, and…
