Cryogenic setup for trapped ion quantum computing
M. F. Brandl, M. W. van Mourik, L. Postler +15
We report on the design of a cryogenic setup for trapped ion quantum computing containing a segmented surface electrode trap. The heat shield of our cryostat is designed to attenua…
Fast ion swapping for quantum information processing
Henning Kaufmann, Thomas Ruster, Christian T. Schmiegelow +6
We demonstrate a SWAP gate between laser-cooled ions in a segmented microtrap via fast physical swapping of the ion positions. This operation is used in conjunction with qubit init…
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,…
Maximizing the information gain of a single ion microscope using bayes experimental design
Georg Jacob, Karin Groot-Berning, Ulrich G. Poschinger +2
We show nanoscopic transmission microscopy, using a deterministic single particle source and compare the resulting images in terms of signal-to-noise ratio, with those of conventio…
