Abstract

Non-technical Abstract: This project explores a promising pathway toward fault-tolerant quantum computing by studying spin-triplet superconductors. These materials may host exotic quantum states that could serve as the foundation for robust quantum bits. The research focuses on fabricating and characterizing high-quality Josephson junctions to detect and control these states, addressing key experimental challenges that have limited progress in the field. In addition to advancing quantum technologies, the project includes a strong educational component. Graduate students will gain hands-on training in quantum materials research, while younger students will be introduced to quantum physics through illustrated books. Public interviews with leading physicists will further promote understanding of advanced science among broader audiences. Together, the research and outreach efforts aim to expand both the frontiers of quantum science and access to it. Technical Abstract: Spin-triplet superconductors offer a unique platform for realizing topological quantum states, including Majorana modes and intrinsic pi-junctions, which are essential building blocks for fault-tolerant quantum computing. However, experimental progress in this field has been severely limited by the technical challenges in fabricating high-quality Josephson junctions and characterizing their quantum properties. This project aims to overcome these barriers through the systematic fabrication and investigation of J
