Atom chips and Rydberg atoms

"Atom chips" allow the manipulation of ultra-cold laser cooled atoms
using micro fabricated wire structures. Current carrying wires on the
chip surface generate inhomogeneous magnetic fields, allowing cold
atoms to be held by the same forces as those in the famous Stern-Gerlach
experiment. By varying the wire currents atoms can be
squeezed into small volumes, and put at specific distances relative to
surfaces.

I will discuss our work at Waterloo using atom chips and Rydberg atoms
to study: 1) the electric-field surface noise that limits ion-trap
based quantum computing, and 2) the development of new "hybrid" quantum
systems, that will combine the benefits of gas-phase neutral atoms
with the scalability and strong interactions of condensed matter
systems.

Work done in collaboration with J. Carter, L. Jones and O. Cherry.
