On March 17, 2025, Assistant Professor Yen-Jui Chang of the School of Intelligent Computing and Quantum Information, along with Distinguished Professor Ching-Jui Chang, Director of the Quantum Information Center at Chung Yuan Christian University (CYCU), represented the university at the globally renowned NVIDIA GTC 2025 Conference in San Jose, California.
They presented their latest research titled “Adaptive Distribution Generator: Powering Split-Step Quantum Walks with CUDA-Q” through a poster session and interactive discussions. The presentation attracted widespread recognition and valuable feedback from international scholars and industry experts in the fields of quantum computing and intelligent systems.
In addition, CYCU Ph.D. student Dylan, under the guidance of Distinguished Professor Ying-Yi Hung from the Department of Electrical Engineering, also presented related research, further demonstrating the university’s robust research capabilities in intelligent computing and quantum information science.
During the NVIDIA GTC 2025 conference, Chung Yuan Christian University (CYCU) actively participated in exhibition tours and enterprise discussions on March 18, gaining in-depth insights into the latest global developments in GPU, Artificial Intelligence (AI), High Performance Computing (HPC), and Quantum Computing.
The CYCU delegation also attended several keynote sessions to stay aligned with cutting-edge industry trends. Notably, they took part in NVIDIA’s inaugural “Quantum Day”, where CEO Jensen Huang and CEOs from leading quantum startups engaged in panel discussions, offering strategic perspectives on the current landscape and future of the quantum industry.
On March 20, CYCU continued its engagement by participating in “Quantum Developer Day”, joining quantum software and hardware developers from around the world. Through technical sessions and collaborative exchanges, the team explored the latest tools, frameworks, and application outcomes in quantum development—actively expanding its global academic and technological network, and reinforcing international research collaborations in quantum science.
In addition to participating in GTC 2025, Assistant Professor Yen-Jui Chang was invited to deliver a special lecture at San José State University (SJSU), a sister university of Chung Yuan Christian University (CYCU). His visit aimed to strengthen academic collaboration between the two institutions, particularly in the fields of quantum computing and artificial intelligence (AI). In recent years, SJSU has been actively developing a Master’s Program in Quantum Technology, fostering interdisciplinary talent and laying a solid foundation for future joint initiatives.
CYCU was also invited to visit Google Headquarters, where Distinguished Professor Ching-Jui Chang delivered a 90-minute keynote lecture titled “Quantum + AI: The Rise of a New Civilization.” During the visit, he engaged in in-depth discussions with Google’s engineering teams on the future applications and collaborative potential of AI, cloud computing, and quantum technologies—further deepening CYCU’s academic-industry partnerships and global innovation presence.
Led by Distinguished Professor Ching-Jui Chang and Assistant Professor Yen-Jui Chang, the Quantum Computing Research Team at Chung Yuan Christian University (CYCU) has achieved a significant breakthrough in quantum random walk technology. By integrating GPU-based CUDA architecture with Python’s Cupy library, the team successfully optimized the traditional PageRank algorithm, accelerating its computation speed by up to 10,000 times compared to conventional methods. This advancement opens up new possibilities in complex network analysis and big data processing.
The technique leverages quantum mechanical properties such as superposition, interference, and decoherence to deeply analyze network structures, and uses high-performance parallel computing to drastically reduce processing time—highlighting the transformative potential of quantum computing in real-world high-performance applications.
Professor Ching-Jui Chang remarked,
“The next 30 years will be the golden age of quantum computing. This breakthrough not only showcases CYCU’s leadership in quantum technology but also signals the profound impact quantum computing will have on fields such as materials science, drug discovery, and financial technology.”
