SUMMARY:Superconducting qubits and cavities: sidebands and vortices\, 
 R. G. Herb Condensed Matter Seminar\, Professor Britton Plourde\, Syra
 cuse University
DESCRIPTION:There has been tremendous progress in recent years with th
 e development of superconducting qubits and cavities. I will describe 
 two recent efforts in this area at Syracuse University. We have implem
 ented a frequency-modulated driving technique with asymmetric transmon
  qubits for generating first-order sideband transitions for the rapid 
 exchange of excitations between qubits and cavities. There are a varie
 ty of loss mechanisms that can influence the performance of both super
 conducting cavities and qubits\, including magnetic flux vortices and 
 quasiparticles. We are working on experiments with structures for trap
 ping a single vortex in a superconducting microwave cavity. For certai
 n locations of the vortex in the cavity\, we observe a decrease in the
  microwave loss\, which we attribute to a reduction of the quasipartic
 le density due to interactions with the vortex core.
