The PhD candidate will focus on the development and microfabrication of superconducting quantum devices, such as devices based on Josephson junctions and/or devices based on superconducting high-kinetic-inductance films. The candidate will be involved in the design and simulations and in the microfabrication of the devices, exploiting the cleanroom facilities at Fondazione Bruno Kessler. The cleanroom processes for the microfabrication of the single circuitry elements, such as Josephson junctions, microwave resonators and high-kinetic-inductance films, will be optimized. Subsequently, the optimized processes will be exploited for the fabrication of the final quantum devices, which will be characterized at millikelvin temperature by means of dilution refrigerators. The results of the measurements and of the corresponding data analysis will serve to further optimize the device in order to improve the performance. The optimized devices (Josephson junctions-based devices and/or Kinetic Inductance Travelling Wave Parametric Amplifiers) will be exploited to investigate fundamental physics processes, such as microwave squeezing and generation of entangled microwave photons. The produced devices will be finally combined to create a complete read-out chain for multiqubit systems.
