Superconducting electronic circuits are rapidly becoming central to a wide range of emerging technologies, from quantum information processors and ultra-low-noise amplifiers to precision sensing platforms and high-speed digital logic. As these systems scale in complexity and performance, their operation increasingly hinges on subtle materials considerations, nanoscale design choices, and the precise control of electromagnetic environments. This growing sophistication has made it essential to understand the microscopic mechanisms that ultimately limit coherence, stability, and reproducibility in superconducting devices.
A persistent challenge in these systems is the presence and behavior of quantized magnetic vortices. Even extremely small residual magnetic fields—arising from the ambient environment, trapped flux during cooldown, or local field gradients—can introduce vortices into superconducting films and devices. Once present, these vortices can move, pin, or depin in ways that generate dissipation, shift operating points, reduce coherence, and ultimately degrade device reliability. Developing robust strategies for trapping, controlling, and removing vortices is therefore essential for ensuring reproducible, high-performance operation across the growing landscape of superconducting electronics.
To accelerate progress on these challenges, the V-TRASE workshop brings together leading experimentalists, theorists, and engineers to share results, map out needs, and drive coordinated solutions in vortex trapping, control, and mitigation in superconducting devices of today and tomorrow.
