1. 1. Tunable superconducting resonators, subharmonic oscillations and manipulation of microwaves

   Författare :Ida-Maria Svensson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; circuit-QED; tunable superconducting resonators; subharmonic oscillations; parametric oscillations; microwave manipulation; frequency down-conversion; driven nonlinear systems; superconducting resonator; SQUID; tunable resonator;

   Sammanfattning : In this thesis I present different types of manipulations of microwave fields using tunable superconducting resonators. A resonator is made tunable by adding one or more superconducting quantum interference devices, SQUIDs. The SQUID consists of a superconducting loop with two Josephson junctions and acts as a tunable nonlinear inductor. LÄS MER
