The PhD candidate will focus on the development of superconducting quantum devices, such as superconducting qubits and parametric amplifiers, and on the optimisation of the circuit components, such as Josephson junctions and high-kinetic-inductance components. The candidate will be involved in the design and simulations as well as in the microfabrication and in the cryogenic characterisation of the devices. The produced devices will be exploited to investigate fundamental physics cQED processes in the microwave domain and to be integrated in complete quantum systems.
