Planar Ion Trap Geometry for Microfabrication

We describe a novel high aspect ratio radiofrequency linear ion trap geometry that is amenable to modern microfabrication techniques. The ion trap electrode structure consists of a pair of stacked conducting cantilevers resulting in confining fields that take the form of fringe fields from parallel plate capacitors. The confining potentials are modeled both analytically and numerically. This io...

Quadrupole ion traps and trap arrays: geometry, material, scale, performance.

Quadrupole ion traps are reviewed, emphasizing recent developments, especially the investigation of new geometries, guided by multiple particle simulations such as the ITSIM program. These geometries include linear ion traps (LITs) and the simplified rectilinear ion trap (RIT). Various methods of fabrication are described, including the use of rapid prototyping apparatus (RPA), in which 3D obje...

Application of ion conductors for microfabrication of solid surface

The present paper describes novel microfabrication techniques which utilize an ion migration at the microcontact between ion conductor and target solid. Two different methods have been recently proposed by our group. One is a solid state electrochemical route for pinpoint doping using an ion conductor. In this approach, an electric field is applied to the solid­solid interface between the catio...

Ion-Trap Quantum Computation

Quantum computation requires a very special physical environment. Numerous operations must be performed on the quantum states of the qubits (or quantum bits) before those states decohere, or lose the interlocking phase relationships that give quantum computation its power. Thought to be an unavoidable outcome of the interaction between the quantum state and the environment, decoherence threaten...
