Jaw-Shen Tsai was born in 1952. He graduated from department of physics of University of California at Berkeley in 1975 and received his Ph.D. in Physics from State University of New York at Stony Brook in 1983. His research life has been devoted to the study of macroscopic quantum effect in superconductors, especially which associated with Josephson junctions. He has contributed to the area of condensed matter physics in both fundamental physics and their technological potential. The most celebrated work of his is the demonstration of quantum coherent oscillations in a solid state system. He is a Fellow at NEC Nano Electronics Research Laboratories, where he leads the Josephson junction based qubit project. He is also the Laboratory Head of Macroscopic Quantum Coherence Research laboratory, Advanced Science Institute, RIKEN. He joined NEC R&D unit in 1983, and since 1996 he has been working on the experiments connected quantum coherence in the Josephson systems. In this direction, his group has been pioneering the science and technology of superconducting quantum computing. His group has demonstrated the first solid-state based qubit in 1999, and subsequently demonstrated the first solid state CNOT gate in 2003, a switchable coupling between qubits required for a quantum universal gate in 2007. He received Nishina Memorial Prize in 2004 and Simon Memorial Prize in 2008. He is a fellow of American Physical Society and is an Honorary Professor of National Chiao Tung University, Taiwan.
