Director KIM Kihwan
Director Kim received his Ph.D. in Physics from Seoul National University. He subsequently conducted postdoctoral research at Seoul National University, the University of Innsbruck (Austria), and the University of Maryland (USA). Since 2011, he has served as a professor in the Department of Physics at Tsinghua University, where he has led an internationally recognized research program. He is a world-leading expert in trapped-ion quantum science. His research uses the internal energy states of trapped ions as qubits, with quantum states precisely controlled and measured using laser-based techniques. Through the trapped-ion approach, he has significantly advanced the understanding of the fundamental limits of quantum systems and has led the development of key quantum platforms, including quantum computers, quantum simulators, and quantum metrology systems.
The Center for Trapped Ion Quantum Science aims to build large-scale quantum systems in which the quantum world can be precisely initialized, manipulated, and measured at will using trapped-ion technology. Starting from small quantum devices with ultra-precise control of individual ions, the center seeks to progressively scale up system size and complexity. Through this approach, the center addresses fundamental questions regarding how far the size, controllability, and computational power of quantum systems can be extended, thereby laying the groundwork for next-generation quantum technologies.
Based on trapped-ion systems, the center conducts leading research in quantum information science by exploring the ultimate scalability of precisely controllable quantum systems. Its major research activities include:
