Abstract
Over the past decade, numerous reputable companies, including IBM, Google, Microsoft, and various startups, have invested substantial resources in industrial research on quantum computing and the development of quantum computers. These quantum computers rely on qubits, or quantum bits, as their fundamental components, with information transmission facilitated by low-power microwave fields. Consequently, achieving ultra-low-noise microwave amplification is of paramount importance for accurately measuring these microwave fields and determining qubit state information. Parametric amplification emerges as a highly effective technique for conducting precise microwave measurements on quantum circuits. Parametric amplification, featuring Josephson Junctions, has been a well-established method for some time. However, recent advancements have introduced kinetic inductance as a non-linear superconducting phenomenon, leading to improved parametric amplifier designs. This thesis delves into a study of superconducting resonators, which serve as the core component of kinetic-inductance parametric amplifiers.
