1. 1. Fractal superconducting resonators for the interrogation of two-level systems

   Författare :Sebastian Erik de Graaf; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cooper-pair box; decoherence; electron spin resonance; two-level systems; atomic force microscopy; quasiparticles; near-field scanning microwave microscopy; Superconducting resonators; circuit quantum electrodynamics;

   Sammanfattning : In this thesis we use high-Q superconducting thin-film microwave resonators to interact with several types of quantum mechanical two-level systems. Such a resonator is used as the central building block in a cryogenic near-field scanning microwave microscope (NSMM) to reach a completely new regime of NSMM operation. LÄS MER

3. 2. Slow propagation line-based superconducting devices for quantum technology

   Författare :Astghik Adamyan; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; superconducting transmission line; electron spin resonance; parametric amplifier; near field scanning microwave microscopy; tunable microstrip resonator;

   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).
