- Quantenlimitierte Josephson Parametrische Verstärker für das Ku-Band
Josephson parametric amplifiers (JPAs) are key components in the broad and thriving area of quantum information processing with superconducting circuits. Nowadays, they allow for quantum-limited amplification of microwave signals at the frequencies of several GHz. Thereby, they enable efficient quantum state tomography of various systems and detection of extremely weak microwave signals. Extending these devices into the higher frequency range has many practical reasons such as potential improvement of JPA amplification properties. Additionally, there is a big interest in high-frequency JPAs in dark matter axion search experiments, where quantum-limited sensitivity is the key at the frequencies between 10 to 100 GHz corresponding to the axion mass.
In this project, we plan to develop and fabricate flux-driven superconducting JPA designs applicable for the Ku-band frequencies. We will investigate the impact of quasiparticle and surface losses on amplification properties in the proposed frequency range. Finally, we intend to characterize and optimize gain and noise properties of the newly developed JPAs.
The master project consists of designing superconducting Josephson parametric amplifiers, fabricating the latter with electron beam lithography and aluminum shadow evaporation techniques, and performing cryogenic microwave measurements.
