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…
