Two-Dimensional Array of Ion Traps on a Planar Chip

Abstract

We investigate a planar ion chip design with a two-dimensional array of linear ion traps for the scalable quantum information processor. The segmented electrodes reside in a single plane on a substrate and a grounded metal plate, a combination of appropriate rf and DC potentials are applied to them for stable ion confinement, and the trap axes are located above the surface at a distance controlled by the electrodes' lateral extent and the substrate's height as discussed. The potential distributions are calculated using static electric field qualitatively. This architecture is conceptually simple and many current microfabrication techniques are feasible for the basic structure. It may provide a promising route for scalable quantum computers.

Folic Acid‐Navigated and β‐Cyclodextrin‐Decorated Carbon‐Encapsulated Iron Nanoparticles as the Nanotheranostic Platform for Controlled Release of 5‐Fluorouracil

“…The metallic iron core is encapsulated in the tight carbon coating which is made of few-layer graphene . [21][22][23][24] The carbon coating in CEINs is to protect the metallic core against oxidation and agglomeration or aggregation. Carbon-encapsulated iron nanoparticles have better magnetic performance in comparison to iron oxides.…”
