A large scale quantum computer is best constructed using a modular approach. Joining with researchers from the University of Sussex (UK), Google (USA), Aarhus University (Denmark) and RIKEN (Japan), we present the blueprint for an ion trap based scalable quantum…
The prospect of quantum-simulating lattice gauge theories opens exciting possibilities for understanding fundamental forms of matter. Together with colleagues from the University of Innsbruck (Austria), we show that trapped ions represent a promising platform in this context when simultaneously exploiting…
Using trapped atomic ions, we demonstrate a tailored and versatile effective spin system suitable for quantum simulations and universal quantum computation. By microwave control, the sign and effective strength of spin-spin couplings can be changed even during the course of…
Precision sensing, and in particular high precision magnetometry, is a central goal of research into quantum technologies. For magnetometers, often trade-offs exist between sensitivity, spatial resolution, and frequency range. In a collaboration with theorists from Huazhong University of Science and…
We describe the statical and dynamical properties of ions stored in segmented electrodynamical Paul traps with a uniform ion separation. This specific ion arrangement is achieved by a smooth anharmonic effective potential generated by suitable voltages applied to segmented dc…
