1. A device for controlling trapped ions, the device comprising:
a first substrate;
a second substrate disposed over the first substrate;
one or a plurality of first level ion traps configured to trap ions in a space between the first substrate and the second substrate;
one or a plurality of second level ion traps configured to trap ions in a space above the second substrate, to carry out quantum operations between trapped ions in the space above the second substrate, and to read-out qubit states in the space above the second substrate; and
an opening in the second substrate through which ions can be transferred between a first level ion trap and a second level ion trap.
