Segmented movement control electrodes in ion traps

A system comprising:

• at least one radio frequency (RF) electrode extending along a first direction, the at least one RF electrode configured to generate an RF field, wherein a first RF electrode of the at least one RF electrode is disposed in or on a substrate;
• and
• a plurality of direct current (DC) electrodes that are spaced apart along at least the first direction, wherein at least three DC electrodes from the plurality of DC electrodes are spaced apart along a second direction that is different from the first direction, wherein each DC electrode of the at least three DC electrodes is directly adjacent to at least another one of the at least three DC electrodes along the second direction, the at least three DC electrodes configured to generate an electric field, wherein the RF field and the electric field are configured to trap an ion at a first position, the first position being spaced apart from the substrate by a first distance in a third direction, the third direction being different from the first direction and the second direction.
