Predicting electric-field noise in ion traps using fluctuation electrodynamics
Markus Teller, Da An, Alberto M. Alonso +4
Electric-field noise in microfabricated surface ion traps contributes to gate errors in trapped-ion quantum computers, but this noise has been challenging to predict. Here, we pres…
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…

Bassem Badawi, Philip C. Holz, Michael Raffetseder +6
Trapped ions are among the most promising platforms for realizing a large-scale quantum information processor. Current progress focuses on integrating optical and electronic compon…
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…
Controlling two-dimensional Coulomb crystals of more than 100 ions in a monolithic radio-frequency trap
Dominik Kiesenhofer, Helene Hainzer, Artem Zhdanov +4
Linear strings of trapped atomic ions held in radio-frequency (rf) traps constitute one of the leading platforms for quantum simulation experiments, allowing for the investigation…
Integrating a fiber cavity into a wheel trap for strong ion-cavity coupling
Markus Teller, Viktor Messerer, Klemens Schüppert +6
We present an ion trap with an integrated fiber cavity, designed for strong coupling at the level of single ions and photons. The cavity is aligned to the axis of a miniature linea…

Scaling trapped-ion quantum computing will require robust trapping of at least hundreds of ions over long periods, while increasing the complexity and functionality of the trap its…
Electric field noise in a high-temperature superconducting surface ion trap
Philip C. Holz, Kirill Lakhmanskiy, Dominic Rathje +3
Scaling up trapped-ion quantum computers requires new trap materials to be explored. Here, we present experiments with a surface ion trap made from the high-temperature superconduc…
Heating of a trapped ion induced by dielectric materials
Markus Teller, Dario A. Fioretto, Philip C. Holz +8
Electric-field noise due to surfaces disturbs the motion of nearby trapped ions, compromising the fidelity of gate operations that are the basis for quantum computing algorithms. W…

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…
Operation of a planar-electrode ion-trap array with adjustable RF electrodes
Muir Kumph, Philip Holz, Kirsten Langer +4
One path to realizing systems of trapped atomic ions suitable for large-scale quantum computing and simulation is to create a two-dimensional array of ion traps. Interactions betwe…
Infinite density for cold atoms in shallow optical lattices
