We study superconductors in extreme conditions (High Magnetic Fields, High Pressure) to disclose the interplay of different mechanisms involving charge, phonons and magnetic moment. We exploit high-Tc superconductors for the realization of microwave resonant devices. Superconducting qubits are also target of our research, in particular with the aim of develop microwave photon detectors.
