Pusan National University Embarks on Developing Core ‘Topological Superconductors’ for Next-Generation Quantum Computers

Pusan National University (President Choi Jaewon) has been exclusively selected for the “Core Basic Source Research for Next-Generation Quantum Science and Technology” project, supported by the Ministry of Science and ICT and the National Research Foundation of Korea. The university will embark on developing “topological superconductors,” a core foundational technology for next-generation quantum computers.

This research aims to develop three-dimensional topological superconductors, which are a type of superconductor characterized by strong resistance to information loss and excellent noise tolerance.

Topological superconductors are considered next-generation materials that can dramatically enhance the stability and performance of future quantum computers, as they contain unique quantum states (Majorana states) within them.

From this year through 2029, the research team will invest a total of 4.7 billion won (4.5 billion won in national funding and 200 million won in local funding) over five years to pursue: △ the development of high-quality topological superconducting materials, △ securing measurement technologies for properties under ultra-low temperature and high magnetic field environments, and △ elucidating topological superconducting phenomena through various verification methods.

Through these efforts, the university plans to foster the Busan, Ulsan, and Gyeongnam regions as domestic hubs for quantum materials research, while also strengthening connections with local manufacturing and advanced industries.

The project involves Professors Ok Jongmok, Park Sungkyun, and Hwang Chungyu from Pusan National University; Professor Oh Yoonseok from UNIST; Professor Cho Kilyoung from KAIST; Professor Seo Soonbeom from Changwon National University; and Dr. Jang Dongjin and Dr. Ham Ungdon from the Korea Research Institute of Standards and Science. The research team will conduct integrated research encompassing the entire cycle, from single crystal growth and theoretical model calculations to ultra-low temperature physical property measurements and verification of topological superconducting characteristics.

Professor Ok Jongmok stated, “This project is a globally challenging field, and if successful, it will mark an important turning point for Korea, beyond Busan, to lead research in quantum materials. We will contribute to preparing for the upcoming Quantum Era.”
