Ion Trapping With Integrated Electromagnets
Devices, systems, and methods for ion trapping with integrated electromagnets are described herein. One device includes a plurality of electrodes configured to trap an ion above a surface of the device, a medial coil and a plurality of peripheral coils, each positioned at a respective radial angle associated with the medial coil, wherein the medial coil is configured to generate a first magnetic field having a first orientation, and wherein the peripheral coils are configured to generate a second magnetic field having a second orientation that opposes the first orientation.

- 1. A device for ion trapping, comprising:
a plurality of electrodes configured to keep a location of an ion static adjacent to an exterior surface of the device; a coil configured to generate a first magnetic field having a first orientation; and a plurality of peripheral coils, each positioned at a respective radial angle associated with the coil; wherein the peripheral coils are configured to generate a second magnetic field having a second orientation that opposes the first orientation.
- 10. A system, comprising:
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.
- 16. A method for ion trapping, comprising generating a uniform magnetic field using a plurality of Helmholtz coils;
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.
