A long-lived Zeeman trapped-ion qubit
Thomas Ruster, Christian T. Schmiegelow, Henning Kaufmann +3
We demonstrate a coherence time of 2.1(1)~s for electron spin superposition states of a single trapped Ca ion. The coherence time, measured with a spin-echo experiment,…
Experimental realization of fast ion separation in segmented Paul traps
Thomas Ruster, Claudia Warschburger, Henning Kaufmann +7
We experimentally demonstrate fast separation of a two-ion crystal in a microstructured segmented Paul trap. By the use of spectroscopic calibration routines for the electrostatic…
Quantum Magnetism of Spin-Ladder Compounds with Trapped-Ion Crystals
A. Bermudez, J. Almeida, K. Ott +6
The quest for experimental platforms that allow for the exploration, and even control, of the interplay of low dimensionality and frustration is a fundamental challenge in several…
