Different atoms and ions possess characteristic energy levels. Like a fingerprint, they are unique for each species. Among them, the atomic ion 173 Yb + has attracted growing interest because of its ...

Nuclear effect The deformed shape of the ytterbium-173 nucleus (right) makes it possible to excite the clock transition with a relatively low-power laser. The same transition is forbidden (left) if ...

A new cooling technique that utilizes a single species of trapped ion for both computing and cooling could simplify the use of quantum charge-coupled devices (QCCDs), potentially moving quantum ...

We developed a surface-electrode ion trap with a square hole measuring \(40\,\mathrm {\mu m}\) for atomic loading. The hole was fabricated using anisotropic etching of a silicon substrate and was ...
