Abstract Two-dimensional (2D) ion crystals may represent a promising path to scale up qubit
numbers for ion trap quantum information processing. However, to realize universal …

A large qubit capacity and an individual readout capability are two crucial requirements for
large-scale quantum computing and simulation. As one of the leading physical platforms for …

The prospect of quantum-simulating lattice gauge theories opens exciting possibilities for
understanding fundamental forms of matter. Here, we show that trapped ions represent a …

In this study, we report about the design, fabrication, and operation of a Cu-filled through-
silicon via (TSV)-integrated ion trap. TSVs are placed directly underneath electrodes as …

Trapped-ion systems are a leading platform for quantum information processing, but they
are currently limited to 1D and 2D arrays, which imposes restrictions on both their scalability …

Phase transitions have been a research focus in many-body physics over past decades.
Cold ions, under strong Coulomb repulsion, provide a repealing paradigm of exploring …

The spin-boson model is a prototypical model for open quantum dynamics. Here we
simulate the spin-boson model using a chain of trapped ions in which a spin is coupled to a …

We study the Doppler-cooling of radial two-dimensional (2D) Coulomb crystals of trapped
barium ions in a radiofrequency trap. Ions in radial 2D crystals experience micromotion of an …

large-scale quantum computing and simulation. As one of the leading physical platforms for …

We study discrete solitons (kinks) accessible in the state-of-the-art trapped ion experiments,
considering zigzag crystals and quasi-three-dimensional configurations, both theoretically …
