Hyperfine energy levels in trapped ions offer long-lived spin states. In addition, the motion of these charged particles couples strongly to electric field perturbations. These characteristics make ...

The atmospheric electric field (AEF) is an important electrical phenomenon that occurs between the Earth’s surface and the ionosphere. It is primarily formed by negative charges on the surface and ...

A new quantum sensing approach could dramatically improve how scientists measure low-frequency electric fields, a task that has long been limited by bulky setups and blurry resolution. Instead of ...
