Device for controlling trapped ions with electrode circuitry configured for device testing

An apparatus for controlling trapped ions includes a substrate. An electrode structure is disposed on the substrate, the electrode structure including a DC electrode and an RF electrode of an ion trap configured to trap ions in a space above the substrate. A first device terminal is disposed on the substrate, the first device terminal being connected to the specific DC electrode via a first electrode connection line. Further, a second device terminal is provided on the substrate, the second device terminal being connected to the specific DC electrode via a second electrode connection line. 用于控制俘获离子的设备包括基板。电极结构设置在基板上，电极结构包括离子阱的DC电极和RF电极，所述离子阱被配置成俘获在基板上方的空间中的离子。第一设备端子设置在基板上，第一设备端子经由第一电极连接线而连接到特定DC电极。此外，第二设备端子设置在基板上，第二设备端子经由第二电极连接线而连接到特定DC电极。
