1. Slow propagation line-based superconducting devices for quantum technology
Sammanfattning : In the field of circuit quantum electrodynamics (c-QED), the coherent interaction of two-level systems (TLSs) with photons, confined in a superconducting microwaveresonator, opens up new possibilities for quantum computing experiments.This thesis contributes to the expansion of c-QED tool-box with slow propagation line-based solutions for ubiquitous techniques, such as cryogenic Near Field Scanning Microwave Microscopy (NSMM), Electron Spin Resonance (ESR) spectroscopy and Traveling Wave Parametric Amplifier (TWPA).

2. Parametrically pumped superconducting circuits
Sammanfattning : 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).

3. Tunable superconducting transmissionline resonator for qubit coupling
Sammanfattning : 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. LÄS MER
4. Superconducting High Speed Passive Interconnects
Sammanfattning : Superconducting digital RSFQ technology offers unique digital processing solutions for the telecommunication that allows more than three times increasing capacity of the 3G networks, makes telecommunication receivers reconfigurable and adjustable for different services, and significantly enhances security level of the data transfer over the fibers.Key features of RSFQ technology are high speed, low power and high integration density.

5. Quantum Optics with Propagating Microwaves in Superconducting Circuits
Sammanfattning : We address recent advances in quantum optics with propagating microwavesin superconducting circuits. This research field exploits on the fact that the coupling between a superconducting artificial atom and propagating microwave photons in a one-dimensional (1D) open transmission line can be made strong enough to observe quantum effects, without using any cavity to confine the microwave photons.
