Join us for a groundbreaking international workshop at Kyushu University from September 9-11, 2024. This event sets itself apart from other quantum and cryogenic computing conferences by focusing on four key themes:

  • Application/Software

  • Algorithm/Architecture

  • Circuit/Device

  • Fabrication

By bringing together diverse expertise, we aim to cultivate holistic solutions, paving the way for significant advancements in various low-temperature computing applications, including quantum computing. While the workshop includes a brief tutorial segment for students and young professionals, the main emphasis is on encouraging interdisciplinary dialogue and collaboration. We are committed to exploring comprehensive solutions that transcend traditional boundaries in quantum computing. Join us in shaping a future where quantum computing takes a qualitative leap forward, powered by collaborative innovation and cross-disciplinary insights.

Jaw-Shen Tsai was born in 1952 in Taipei. He graduated from department of physics of University of California at Berkeley in 1975 and subsequently received his Ph.D. in Physics from State University of New York at Stony Brook. 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. He led the Josephson-junction-based qubit project at NEC Tsukuba laboratory for many years. He is also the Team Leader of Macroscopic Quantum Simulation Team in RIKEN Center for Quantum Computing.

Since 2015, he is professor of physics at Tokyo University of Science. 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 by demonstrating the first solid-state based qubit (1999), the first solid state CNOT gate (2003), a universal quantum gate operation (2007). Moreover, many important results relating to the quantum optics with artificial superconducting atom were demonstrated. He received Nishina Memorial Prize in 2004, Simon Memorial Prize in 2008, Leo Esaki Prize in 2014, Medal with Purple Ribbon in 2018, Asahi Prize in 2021, Japan Academy Prize, Houko Prize, and C & C Prize in 2023. He is a fellow of American Physical Society and a fellow of Japan Society of Applied Physics.

Kazutoshi Kobayashi received his B.E., M.E. and Ph. D. in Electronic Engineering from Kyoto University, Japan in 1991, 1993, 1999, respectively. Starting as an Assistant Professor in 1993, he was promoted to an Associate Professor in the Graduate School of Informatics, Kyoto University in 2001, and stayed in that position until 2009. For two years during this time, he acted as an Associate Professor of VLSI Design and Education Center (VDEC) at the University of Tokyo.  Since 2009, he has been a Professor at Kyoto Institute of Technology. While in the past he focused on reconfigurable architectures utilizing device variations, his current research interest is in improving the reliability (Soft Errors, Bias Temperature Instability and Plasma Induced Damage) of current and future VLSIs. He started a research project related to gate drivers for GaN and SiC transistors since 2013.

In 2022, he was nominated for one of the project managers of Moonshot Goal 6 "Realization of a fault-tolerant universal quantum computer that will revolutionize economy, industry, and security by 2050" and organized his project team named "Development of Scalable Highly Integrated Quantum Bit Error Correction System" abbreviated as QUBECS. He was the recipient of the IEICE best paper award in 2009, the IRPS best poster award in 2013, the ICICDT best paper award in 2019 and the IEICE Electronics Society award in 2021.

Classical Electronics to Control Qubits and Correct Errors in Room-temperature and Cryogenic Environments



Nobuyuki Yoshikawa currently serves as a professor at the Institute of Advanced Sciences (IAS) at Yokohama National University (YNU), where he leads the superconductivity electronics group.

He earned his Ph.D. in Electrical and Computer Engineering (ECE) from YNU in 1989 and has since been affiliated with YNU's ECE Department.

His research primarily centers on superconductive devices and their integration into digital and analog circuits. Presently, his focus is on developing highly energy-efficient superconducting digital circuits, particularly those that employ Adiabatic Quantum-Flux Parametron (AQFP) and Single Flux Quantum (SFQ) logic, with an aim towards high-performance computing applications. Yoshikawa has authored or co-authored over 300 journal publications. In 2023, he was honored with the IEEE Council on Superconductivity (CSC) Award for Continuing and Significant Contributions in the field of applied superconductivity. He is also a Fellow of the IEEE.
