  • Abstract: The QCT group at IFAE studies applications of superconducting quantum circuits in quantum science and quantum technologies. In this talk, I will give an overview of the group activities by focusing on the efforts to study the impact of ionizing radiation on qubits and how to mitigate it, as well as the development of superinductor-based circuits. I will first describe the ICRQ project in which suppression of environmental radioactivity and cosmic rays is implemented on a standard laboratory above ground. On the second part of the talk, I will introduce nitridized aluminum as a new disordered superconductor with potential for being used as a superinductor. I will also show ongoing efforts to couple a flux qubit to a superconducting resonator using a granular aluminum wire.
