Deterministic reordering of 40Ca+ ions in a linear segmented Paul trap
F. Splatt, M. Harlander, M. Brownnutt +3
In the endeavour to scale up the number of qubits in an ion-based quantum computer several groups have started to develop miniaturized ion traps for extended spatial control and ma…
State-independent experimental test of quantum contextuality
G. Kirchmair, F. Zähringer, R. Gerritsma +5
The question of whether quantum phenomena can be explained by classical models with hidden variables is the subject of a long lasting debate. In 1964, Bell showed that certain type…
The geometric measure of entanglement for symmetric states
R. Hübener, M. Kleinmann, T. -C. Wei +2
Is the closest product state to a symmetric entangled multiparticle state also symmetric? This question has appeared in the recent literature concerning the geometric measure of en…
Experimental violation of a Bell inequality with two different degrees of freedom of entangled particle pairs
Xiao-song Ma, Angie Qarry, Johannes Kofler +2
We demonstrate hybrid entanglement of photon pairs via the experimental violation of a Bell inequality with two different degrees of freedom (DOF), namely the path (linear momentum…
Observation of strong coupling between a micromechanical resonator and an optical cavity field
Simon Groeblacher, Klemens Hammerer, Michael R. Vanner +1
Achieving coherent quantum control over massive mechanical resonators is a current research goal. Nano- and micromechanical devices can be coupled to a variety of systems, for exam…
Practical methods for witnessing genuine multi-qubit entanglement in the vicinity of symmetric states
Geza Toth, Witlef Wieczorek, Roland Krischek +3
We present general numerical methods to construct witness operators for entanglement detection and estimation of the fidelity. Our methods are applied to detecting entanglement in…
