Abstract
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.
Claims20
A device for ion trapping, comprising:
- a plurality of electrodes configured to trap an ion above a surface of the device;
- a medial coil below the surface of the device;
- and
- a plurality of peripheral coils below the surface of the device, 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.
A system, comprising:
- a first medial coil configured to generate a first upward magnetic field;
- four first peripheral coils positioned to surround the first medial coil and configured to generate a first downward magnetic field;
- a second medial coil located a particular distance from the first medial coil and configured to generate a second upward magnetic field;
- and
- four second peripheral coils positioned to surround the second medial coil and configured to generate a second downward magnetic field.
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 to surround 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 to surround 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.
