Demonstration of transport in an ion trap design for two-dimensional lattices
Michael Pfeifer, Marco Valentini, Matthias Dietl +7
Microfabricated ion trap chips are at the core of some of the most advanced quantum computers. How a large number of ions is arranged and controlled on an ion trap chip depends on…
Demonstration of a Multiplexing Trapped Ion Quantum Processing Unit
F. Anmasser, M. Abu Zahra, K. Schüppert +9
A fault-tolerant quantum computer is expected to require thousands of qubits. Trapped ion architectures provide a modular approach where the quantum register is divided into multip…
Demonstration of two-dimensional connectivity for a scalable error-corrected ion-trap quantum processor architecture
Marco Valentini, Martin W. van Mourik, Friederike Butt +12
A major hurdle for building a large-scale quantum computer is increasing the number of qubits while maintaining connectivity between them. In trapped-ion devices, this connectivity…
Femtosecond laser written waveguides in sapphire for visible light delivery
Sarah Winkler, Joachim R. Krenn, Jakob Wahl +8
A promising solution for scalable integrated optics of trapped-ion quantum processors are curved waveguides guiding visible light within sapphire bulk material. To the best of our…
Observation of superconductivity and surface noise using a single trapped ion as a field probe
K. Lakhmanskiy, P. C. Holz, D. Schärtl +5
Measuring and understanding electric field noise from bulk material and surfaces is important for many areas of physics. In this work, we introduce a method to detect in situ diffe…
