Research Directions

　　In recent years, Xiao-Hui Song has concentrated on the fabrication and low-temperature performance of high-quality superconducting quantum devices. She has gained substantial expertise in improving thin-film fabrication equipment, optimizing fabrication processes, and advancing micro-nano processing technologies. She has fabricated multiple multi-qubit superconducting quantum devices with long decoherence times and explored the application of flip-chip and through-silicon via technologies in multi-qubit device fabrication. She has also refined the fabrication process and design principles of Josephson parametric amplifiers, producing high-gain, wide-bandwidth amplifiers that enable single-shot qubit measurements.
