11. Parametrically pumped superconducting circuits
Abstract : In this licentiate thesis, I present the design, fabrication, and characterization of superconducting parametric resonators, for use in quantum information processing. These devices are quarter-wavelength coplanar waveguide resonators (~5 GHz), terminated at one end by a non-linear inductance provided by a SQUID (superconducting quantum interference device).

12. Key Components for High Tc SQUID Magnetometers
Abstract : This thesis describes the development of key components for superconducting quantum interference device (SQUID) magnetometers in the high temperature superconductor YBa2Cu3O7 (YBCO). Such magnetometers are made for liquid nitrogen temperature operation, as opposed to low Tc devices that are confined to liquid helium. READ MORE

13. The Josephson parametric oscillator - From microscopic studies to single-shot qubit readout
Abstract : Circuit quantum electrodynamics (cQED) is a prominent platform for quantum information processing, in which microwave photons are confined into resonant cavities coupled to superconducting quantum bits (qubits). The large effective dipole moment of the qubit, in combination with the high energy density of the quasi 1-D resonator allow these systems to enter the so-called strong coupling regime. READ MORE

14. Tunable superconducting resonators, subharmonic oscillations and manipulation of microwaves
Abstract : 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. READ MORE

15. Nanoscale structure forming processes : Metal thin films grown far-from-equilibrium
Abstract : Thin film growth from the vapor phase has for a long time intrigued researchers endeavouring to unravel and understand atomistic surface processes that govern film formation. Their motivation has not been purely scientific, but also driven by numerous applications where this understanding is paramount to knowledge-based design of novel film materials with tailored properties.
