Shuttling-Based Trapped-Ion Quantum Information Processing
V. Kaushal, B. Lekitsch, A. Stahl +7
Moving trapped-ion qubits in a microstructured array of radiofrequency traps offers a route towards realizing scalable quantum processing nodes. Establishing such nodes, providing…
A spin heat engine coupled to a harmonic-oscillator flywheel
David von Lindenfels, Oliver Gräb, Christian T. Schmiegelow +6
We realize a heat engine using a single electron spin as a working medium. The spin pertains to the valence electron of a trapped Ca ion, and heat reservoirs are emulate…
Scalable creation of long-lived multipartite entanglement
H. Kaufmann, T. Ruster, C. T. Schmiegelow +6
We demonstrate the deterministic generation of multipartite entanglement based on scalable methods. Four qubits are encoded in Ca, stored in a micro-structured segmented…
Entanglement-based dc magnetometry with separated ions
T. Ruster, H. Kaufmann, M. A. Luda +4
We demonstrate sensing of inhomogeneous dc magnetic fields by employing entangled trapped ions, which are shuttled in a segmented Paul trap. As \textit{sensor states}, we use Bell…
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…
