“Ion trap technologies for quantum information science”

Abstract

The application of trapped ions to quantum information science presents a grand challenge premised on the integration of many unusual technologies into a single system. In this talk, I present results from four experiments which bridge between trapped ion quantum computation and areas of condensed matter physics and optical communicatoin. These are demonstrations of (1) superconducting ion traps, suitable for integration of solid-state quantum devises, (2) a transparent-conductor ion trap, made of indium tin-oxide, (3) ion traps fabricated around an integrated optical fiber, and (4) ion traps fabricated on the surface of a high-reflectivity mirror, suitable for high-finesse cavity quantum-electrodynamics. We also have preliminary results from characterizing single ions trapped above a surface made of graphene, in a system which offers novel opportunities for quantum probes of surface physics.
