Symposium NM02-Superconducting Materials and Applications

The symposium will broadly cover the advances in current and emerging superconducting materials from both fundamental and applications perspective. It includes novel and customized superconducting materials for electronics, such as quantum computation, and large-scale superconducting applications, such as prototype superconducting power devices, conductors for high field magnets, accelerators, and newly proposed compact fusion reactors. Overall, in this symposium we intend to cover the rapid progress made worldwide in both application and fundamental understanding of superconducting materials. A key focus of this symposium is to promote the transition from basic science discovery to technology deployment. The emphasis will be on superconducting quantum limited sensors and superconducting qubit with related technologies. We will address the challenges for the development of superconducting qubits that requires material perfection achievable through the identification of the noise sources in the system, and a clear understanding of the influence of the solid-state environment on the sudden long-term fluctuations of the qubit parameters.

For large scale applications, we will focus on high performance, homogeneity through length, cost-effectiveness, high throughput and scalability. The superconducting materials of interests include conventional low temperature superconductors for electronics and sensors, intermetallic superconductors (Nb-Ti, Nb₃Sn), medium- and high-temperature superconductors (cuprates, iron-based compounds, MgB₂), superconducting multi-layers and composites, the recently discovered very high-temperature hydride superconductors and other emergent materials exhibiting unconventional superconductivity like topological superconductors. Symposium contributors in the area of materials are encouraged to address issues including: 1) response of superconductivity to structural, chemical, and defect tuning; 2) improvement of existing practical materials; 3) synthesis, growth mechanisms, high throughput fabrication routes, and; 4) methods to improve application-relevant properties such as flux pinning.

Topics will include:

Superconducting qubit–materials issues, gates and error corrections
Josephson junction technology and interface
Topological superconductors and unconventional superconductivity
REBCO wires and Coated Conductors–processing and applications
Fe-based superconductors and potential applications
Bi-based, Nb-based, MgB2 tapes and round wires–processing and applications
Flux pinning and critical currents–intrinsic pinning behavior, anisotropy, irradiation effect
Energy applications and devices based on superconducting materials
