Director’s words:
  After the establishment of quantum science by Europe in the early 20th century, it has driven a deeper understanding of everything in the universe. Quantum science differs significantly from many concepts in the macro world, such as “quantization” and “uncertainty principle,” causing not only significant changes in technology but also leading to much discussion in humanities and philosophy. The Industrial Revolution utilized mechanics and thermodynamics in physics to allow humanity to enjoy the fruits of mechanical power. The semiconductor revolution used electromagnetics and optics to create the digital world’s fruits. The quantum revolution aims to transform the classical Earth into a quantum Earth. Today, quantum computers are already on the cloud, and the golden period of quantum computer applications has emerged. The quantum Internet will also provide faster and safer endpoint connections. The push for a redistribution of the world’s wealth and power seems to be quietly activated again.

  The emerging metaverse uses innovative digital technologies to allow digital citizens to enter a virtual network world, engage in various real-world activities, realize imagination, and travel freely in various time and space. An ideal metaverse needs to instantly convey various sensations to all digital citizens of the metaverse. The quantum Internet is currently a necessary technology for exploring the metaverse comprehensively and is also the hope to once again promote the high-speed growth of human civilization. With a telescope, “space” can be developed, with a microscope, the “microcosm” can be explored, and quantum technology is the third lens of the world’s civilization.

  The research and development of the Quantum Information Center at Chung Yuan Christian University will focus on the basic research and application of quantum technology and the metaverse and provide basic training and preparation for the Q-generation to enter relevant industries

主任簡介

  Professor Chang Ching-Rei graduated from the Department of Physics at National Taiwan University in 1979. In 1988, he obtained a PhD in Physics from the University of California, San Diego and returned to the Industrial Technology Research Institute’s Magnetic Materials Group the same year. In February 1989, he joined National Taiwan University and has served as Vice President and Acting President of the university.

Since 1982, Professor Chang has been engaged in numerical research on micromagnetics. He is not only a founder of this field, but has also continuously promoted its relevant applications in the magnetic industry. He has made important contributions to both fundamental research and applied technology in the areas of flipping mechanisms and thermal disturbance. In recent years, his research has mainly focused on the spin transport mechanism in low-dimensional materials. Professor Chang has published over 280 professional papers and obtained more than 28 patents related to magnetism. He has been elected as a Fellow of the American Physical Society (APS) and the Institute of Electrical and Electronics Engineers (IEEE) for his outstanding academic achievements, as well as an Academician of the Russian International Academy of Engineering (RIAE).

Professor Chang has served as President of the Asian Magnetic Society, the Taiwan Magnetic Society, and the Taiwan Physics Society. Recently, he has been leading the NTU-IBM Quantum Computing Program, served as the director of IBM-NTU Q hub, and actively cultivating emerging interdisciplinary talents for application in new materials, new drug synthesis, optimization systems, and financial fields. He has been actively promoting quantum computing and founded the Taiwan Quantum Computing and Information Technology Association, serving as its first President. In 2022, Professor Chang became the Chair Professor in the Department of Physics at Chung Yuan Christian University and concurrently serves as the Director of the university-level Quantum Information Center.
