  1. 1. Fast-tunable resonators and quantum electrical circuits

    Author : Martin Sandberg; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SEB; tunable; Sisyphus resistance; CPW; Resonator; SCB; qubit; circuit-QED; transmon; SQUID;

    Abstract : In this thesis, measurements on superconducting electrical circuits that exhibit quantum mechanical effects are presented. Nonlinear superconducting circuits can be regarded as artificial atoms with energy spectra that can be engineered. The artificial atoms can be used as quantum bits for quantum computation. READ MORE

  2. 2. Tunable superconducting transmissionline resonator for qubit coupling

    Author : Martin Sandberg; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fast tuning; superconductivity; transmission line; SCB; Josephson inductance.; Frequency tunable resonator; SQUID; CPW; aluminium;

    Abstract : In this licentiate thesis design, fabrication, and measurements of tunable superconducting microwave transmission line resonators are described. The resonators are of quarter wavelength type were the tuning is achieved by changing one of the boundary conditions of the resonator through a tunable impedance. READ MORE

  3. 3. Gap waveguide for packaging microstrip filters & investigation of transitions from planar technologies to ridge gap waveguide

    Author : Astrid Algaba Brazalez; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; parallel plate mode; coupled line filter; microstrip circuit; packaging; Artificial magnetic conductor AMC ; perfect magnetic conductor PMC ; gap waveguide; transition.; coplanar waveguide CPW ;

    Abstract : Gap waveguide technology has proved to constitute an effective alternative for the design of microwave passive components, due to its advantages with respect to traditional planar technologies and standard waveguides. There is no requirement for conductive contact between the two different metal pieces making up a gap waveguide prototype, since one of these pieces makes use of a textured surface that eliminates any possible leakage of the field through the gap to the surface of the other metal piece above it.
