  2. 1. Degenerate and nondegenerate Josephson parametric oscillators for quantum information applications

    Author : Andreas Bengtsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantum information; superconducting circuits; multimode; circuit quantum electrodynamics; SQUID; Parametric oscillations;

    Abstract : Parametric oscillations are well studied phenomena, with applications in amplification, quantum optics, and quantum information processing. They can occur as a parameter of a system, such as the resonant frequency, is being modulated or “pumped” by an external field. READ MORE

  4. 2. Parametric interactions with signals and the vacuum

    Author : Michael Roger Andre Simoen; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; vacuum; circuit-QED; interferometer; SQUID; dynamical Casimir effect; multimode resonator; pumpistor; mode conversion; superconducting circuits; parametric amplification;

    Abstract : In this thesis I present different experiments on superconducting circuits exploring parametric interactions with external signals and the vacuum in the microwave regime. These parametric processes are the result of the periodic modulation of a property of a system which results in different interactions. READ MORE

  5. 3. Quantum information processing with tunable and low-loss superconducting circuits

    Author : Andreas Bengtsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; parametric modulation; quantum information; high coherence; superconducting circuits; circuit quantum electrodynamics;

    Abstract : The perhaps most promising platform for quantum information processing is the circuit-QED architecture based on superconducting circuits representing quantum bits. These circuits must be made with low losses so that the quantum information is retained for as long as possible. READ MORE

  6. 4. Development and Validation of a Numerical Tool for the Aeromechanical Design of Turbomachinery

    Author : María Angélica Mayorca; Torsten Fransson; Damian Vogt; Eric Seinturier; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aeromechanical design; turbomachinery; numerical tool; reduced order modeling; mistuning; ROM; aero-structure coupling; CFD; FEM; methods; Mechanical energy engineering; Mekanisk energiteknik;

    Abstract : In aeromechanical design one of the major rules is to operate under High Cyclic Fatigue (HCF) margins and away from flutter. The level of dynamic excitations and risk of HCF can be estimated by performing forced response analyses from blade row interaction forces or Low Engine Order (LEO) excitation mechanisms. READ MORE

  7. 5. Numerical Methods for Turbomachinery Aeromechanical Predictions

    Author : Maria Angelica Mayorca; Damian Vogt; Torsten Fransson; Robert Kielb; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aeromechanics; numerical tools; methods; turbomachinery; aeroelasticity; gas turbines; vibrations;

    Abstract : In both aviation and power generation, gas turbines are used as key components. An important driver of technological advance in gas turbines is the race towards environmentally friendly machines, decreasing the fuel burn, community noise and NOx emissions. READ MORE
