We propose a novel experiment, the Canfranc Axion Detection Experiment (CADEx), to
probe dark matter axions with masses in the range 330–460 μeV, within the W-band (80 …

The experiment for cryogenic large-aperture intensity mapping (EXCLAIM) is a balloon-
borne telescope designed to survey star formation in windows from the present to z= 3.5 …

We report on spectroscopic and time-domain measurements on a fixed-frequency concentric
transmon qubit in an applied in-plane magnetic field to explore its limits of magnetic field …

We present a method for improving the performance of microwave coplanar resonators in
magnetic fields, by using narrow superconducting strips of width close to the London …

Aluminum lumped-element kinetic inductance detectors (LEKIDs) sensitive to millimeter-
wave photons have been shown to exhibit high quality factors, making them highly sensitive …

A quantum system constrained to a degenerate energy eigenspace can undergo a nontrival
time evolution on adiabatic driving, described by a non-Abelian Berry phase. This type of …

In this thesis I describe work on developing theoretical and numerical models of supercon-
ducting thin-film microwave resonators. Superconducting resonators are used in a variety of …

Abstract Theory of linear microwave response of thin films of type-II superconductors in the
mixed state is developed taking into account random spatial fluctuations of the parameters of …

We show measurements of thermal kinetic inductance detectors (TKIDs) intended for
millimeter-wave cosmology in the 200–300 GHz atmospheric window. The TKID is a type of …

Quantum sensing is a vast and emerging field enabling in-situ studies of quantum systems
and hence the development of quantum hybrid systems. This work creates the fundament of …
