1. An apparatus, comprising:
a first shuttling lane comprising first lane elements;
a second shuttling lane comprising second lane elements;
first electrode elements located along the first shuttling lane;
second electrode elements located along the second shuttling lane;
an electrode control circuit connected to each electrode element of the first electrode elements and the second electrode elements; and
a voltage control circuit connected to each electrode element of the first electrode elements and the second electrode elements, wherein the voltage control circuit is configured to selectively provide at least one voltage to one or more electrode elements of the first electrode elements and of the second electrode elements according to signaling from the electrode control circuit, wherein the at least one voltage controls movement of an ion along at least one of the first shuttling lane or the second shuttling lane, wherein providing the at least one voltage to the one or more electrode elements of the first electrode elements and of the second electrode elements comprises providing, to one or more electrode elements of the first electrode elements and of the second electrode elements, at least one of a keeping voltage or a neutral voltage that is of a neutral voltage profile, and further comprises providing, to one or more electrode elements of the first electrode elements and the second electrode elements, a shuttling DAC signal that comprises at least one shuttling voltage of a shuttling voltage profile.
