SUMMARY:Modes are Modes: Parametric quantum information processing in 
 superconducting circuits\, R. G. Herb Condensed Matter Seminar\, Jose 
 Aumentado \, NIST\, Boulder
DESCRIPTION:I will give a brief overview of our work in utilizing para
 metric coupling to process quantum information in superconducting circ
 uits. In the 2nd half\, I will then discuss some of our ideas in conti
 nuously coupled multi-mode parametric circuits\, and how expansion of 
 the mode basis beyond the traditional two modes (signal+idler) can pro
 vide for more complex behavior including\, for instance\, the possibil
 ity of building in directionality\, impedance matching\, and even modi
 fiying the gain-bandwidth constraint. As a simple example\, I will dis
 cuss a 3-mode amplifier which has been realized in our group in an opt
 omechanical circuit.
