PIF2025 - Nano-Engineered High-Temperature Superconductors for Functional Quantum Devices - (PID2024-156025OB-I00)

Superconducting technologies are prime candidates to develop quantum effects into devices. Dissipationless transport of current, generation of high magnetic fields, ultra-sensitive sensors or quantum information systems may be achieved by controlling superconducting parameters at the nanoscale. In particular, superconducting nanostructures are highly promising systems for future green electronics, fluxtronic devices, single-photon detectors, as well as for developments in topological quantum-state engineering. The project aims to explore different nanostructures based on high temperature superconductors combined with other functional oxides which may be used to design novel systems for quantum sensing and computing. Tasks: High Temperature Superconducting nanostructures will be fabricated by using high-resolution lithography tools. Functional properties of nanostructured devices will be explored though electric and magnetic characterization. The effect of temperature, magnetic or electric fields or geometry constrains will be evaluated.
