Planar Ion Trap Geometry for Microfabrication
نویسندگان
چکیده
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 ion trap geometry may form the basis for large scale quantum computers or parallel quadrupole mass spectrometers.

Surface-electrode point Paul trap
We present a model as well as experimental results for a surface electrode radiofrequency Paul trap that has a circular electrode geometry well suited for trapping single ions and two-dimensional planar ion crystals. The trap design is compatible with microfabrication and offers a simple method by which the height of the trapped ions above the surface may be changed in situ. We demonstrate trap...
متن کاملA two-dimensional lattice ion trap for quantum simulation
Quantum simulations of spin systems could enable the solution of problems that otherwise require infeasible classical resources. Such a simulation may be implemented using a well-controlled system of effective spins, such as a two-dimensional lattice of locally interacting ions. We propose here a layered planar rf trap design that can be used to create arbitrary two-dimensional lattices of ions...
متن کاملSurface-electrode architecture for ion-trap quantum information processing
We investigate a surface-mounted electrode geometry for miniature linear radio frequency Paul ion traps. The electrodes reside in a single plane on a substrate, and the pseudopo-tential minimum of the trap is located above the substrate at a distance on the order of the electrodes' lateral extent or separation. This architecture provides the possibility to apply standard microfabrication princi...

Efficient collection of trapped ion fluorescence is critical for high-fidelity qubit detection and ion-photon logical interconnects in ion trap quantum information processing. The expected size of future many-ion processors place scalability requirements for high efficiency optical collection systems. We report the development and testing of a microfabricated planar ion trap with an integrated ...
