Design of superconducting transmission line integrated surface-electrode ion-traps
We fabricated superconducting surface electrode ion traps with integrated microwave coplanar waveguides using direct-write optical lithography and a niobium on sapphire process. We then tested these traps in a closed cycle cryostat and used 28 mW of microwave power to excite rotational transitions …

Physics of Superconducting Travelling-Wave Parametric Amplifiers
Superconducting travelling-wave parametric amplifiers (TWPAs) are ultra-low-noise amplifiers that achieve amplification through the nonlinear kinetic inductance of superconductors. These devices can have near quantum-limited noise performance, and have important applications in quantum information …

The physics of superconducting ring resonators
Superconducting microwave resonators with very high quality factor have been widely used in a large number of low-temperature experiments and applications over the past two decades. Numerous research on linear distributed, either half-wavelength or quarter-wavelength, and lumped element …
