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...

Photodetachment of cold OH- in a multipole ion trap.

The absolute photodetachment cross section of OH- anions at a rotational and translational temperature of 170 K is determined by measuring the detachment-induced decay rate of the anions in a multipole radio-frequency ion trap. In comparison with previous results, the obtained cross section shows the importance of the initial rotational-state distribution. Using a tomography scan of the photode...

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...
