CA21144 - SUPERCONDUCTING NANODEVICES AND QUANTUM MATERIALS FOR COHERENT MANIPULATION (SUPERQUMAP)

Recent years have seen a surge in superconducting quantum electronics, with rapidly rising number of promising devices and systems enabling quantum coherent manipulation and sensing. Present operating technologies use superconducting devices with a constantly increasing number and complexity of active elements. Quantum computation, for example, requires a perfect manipulation of a large number of qubits, often implemented as complex superconducting hybrid devices in arrangements manipulating quantum phase, flux or charge, among others. However, current technologies based on well-established processes face major difficulties in scaling of environment-protected superconducting qubits. Exploring novel quantum materials and phenomena is an alternative route to considerably improve superconducting devices and make a quantum leap in their stability and coherence. Addressing this goal is a huge challenge which requires going beyond presently available networks and projects. The Action will allow a collaborative approach joining together efforts and groups all over Europe, structured around three pathways, (i) the synthesis and characterization of quantum materials with novel topological properties, (ii) the fabrication of sensors and devices exploiting novel superconducting functionalities, and (iii) the generation and coherent manipulation of superconducting states that can create new opportunities in superconducting quantum electronics. Using an open and inclusive approach that joins expertise and capabilities all over Europe, this Action will foster collaborative efforts aiming at disruptive achievements in the field of superconductivity. The results will have impact far beyond the development of new quantum solutions for computation, including sectors such as health and energy.
