a via connecting the first layer portion and the second layer portion.

6. The device of claim 5, wherein each of the peripheral coils includes: (0) (3)

7. The device of claim 1, wherein the coil and the plurality of peripheral coils include a wire composed of at least one of copper and gold. (2) (0)

10. A system, comprising: (5) (4)

a first medial coil configured to generate a first magnetic field in a first direction;

four first peripheral coils positioned to surround the first medial coil and configured to generate a first magnetic field in a second direction;

a second medial coil located a particular distance from the first medial coil and configured to generate a second magnetic field in the first direction; and

four second peripheral coils positioned to surround the second medial coil and configured to generate a second magnetic field in the second direction.

11. The system of claim 10, wherein each of the four first and four second peripheral coils is configured to generate the magnetic field in the second direction with a strength approximately one-fourth a strength of the magnetic field in the first direction generated by either the first medial coil or the second medial coil. (0)

12. The system of claim 10, wherein the magnetic field in the first direction and the magnetic field in the second direction have substantially equivalent magnitudes. (0)

13. The system of claim 10, wherein the distance between the first medial coil and the second medial coil defines a portion of a logic area. (0)

14. The system of claim 10, wherein each of the first and second medial coil and the four first and four second peripheral coils have a radius between 15 and 50 microns and can contain between 60 and 70 windings. (0)

generating a first local upward magnetic field using a first medial coil;

generating four first local downward magnetic fields using four first peripheral coils positioned adjacent to the first medial coil;

generating a second local upward magnetic field using a second medial coil located a particular distance from the first medial coil;

generating four second local downward magnetic fields using four second peripheral coils positioned adjacent to the second medial coil; and

trapping an ion in a space defined by the first medial coil, the second medial coil, two of the four first peripheral coils and two of the four second peripheral coils.

17. The method of claim 16, wherein trapping the ion includes controlling a spin direction of the ion. (0)

18. The method of claim 16, wherein the space is associated with at least one laser that causes ion cooling. (0)

19. The method of claim 16, wherein the method includes creating a magnetic field gradient in the space. (0)

20. The method of claim 16, wherein the method includes shelving the ion in the space for a period of time. (0)
