Zusammenfassung:A micro-fabricated device for controlling trapped ions includes a substrate of a dielectric material or a semiconductor material. A structured electrode layer is disposed above the substrate. The structured electrode layer forms a plurality of electrodes of an ion trap configured to trap ions in a space above the structured electrode layer. The structured electrode layer includes a low phonon density of states layer, referred to as low-PDOS layer, the low-PDOS layer being of TiN or TiW or Ti or W and having a thickness of equal to or greater than 100 nm.
