Title: Hybrid superconducting building blocks for quantum science and technologies

Abstract: Superconducting nanostructures underpin the development of many promising quantum computing approaches and alternatives to conventional classical computing. Most work to date has focused on all-metallic systems. Recent developments in materials synthesis and nanofabrication have enabled devices that combine superconducting and semiconducting properties. These provide new opportunities for quantum science and technology that rely on the interplay between superconductivity, quantum confinement, and the ability to actively tune superconductivity. In this talk, I will provide a few a examples of hybrid superconducting building blocks that we have developed. These experiments enable us to realize unusual correlations between Cooper pairs, can serve as a platform for realizing real-time tunable topological Josephson matter in higher-dimensional parameter spaces, and may form the basis for actively tunable superconducting qubits or low-power trainable classical hardware.
