James Martin: Atom chips and Rydberg atoms

James Martin, University of Waterloo

Abstract

"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.

Jan Kycia: High Bandwidth rf-qpc, Dissipation Effect on a sSET, and a CPW readout

Jan Kycia, Institute for Quantum Computing (IQC)

Abstract

I will describe the work my group has been doing at Waterloo. We are developing a high bandwidth rf-QPC readout to study lateral quantum dot devices. We have also studied the effect of dissipation on a sSET. Another project is aimed at setting up a CPW readout with a DC bias.
