Ion trap for atomic clocks, mass spectrometry, atomic sensing, and quantum computing

Abstract

The disclosed ion trap comprises a plurality of structurally continuous blades and a plurality of recessed control electrodes, wherein the plurality of structurally continuous blades includes at least two structurally continuous RF blades and at least two structurally continuous DC blades, wherein the recessed control electrodes are disposed on or within the structurally continuous blades, and wherein the ion trap is in a ring configuration. The ion trap enables fast readout of optical transitions using stationary laser beams and moving ions. This design fundamentally contrasts with traditional linear Paul traps that employ stationary ions and laser beams that are turned on or off. Because the RF and DC blades are structurally continuous, the trapping potential is continuous and harmonic. Instead of segmenting the blades as conventionally, segmented recessed control electrodes are utilized to reduce voltage noise that causes unwanted heating of the ions. Many benefits and commercial uses are described.
