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…
High fidelity entanglement of 43Ca+ hyperfine clock states
G. Kirchmair, J. Benhelm, F. Zähringer +3
In an experiment using the odd calcium isotope 43Ca+ we combine the merits of a high fidelity entangling operation on an optical transition (optical qubit) with the long coherence…
Deterministic entanglement of ions in thermal states of motion
G. Kirchmair, J. Benhelm, F. Zähringer +3
We give a detailed description of the implementation of a Molmer-Sorensen gate entangling two Ca+ ions using a bichromatic laser beam near-resonant with a quadrupole transition. By…
