27 - 29 OCT | YOKOHAMA JAPAN
2nd International Workshop
on
Quantum, Cryogenic and Superconductive Computing
Call for Papers – Abstract Deadline 31 July 2025
We invite cutting-edge contributions on quantum devices, cryogenic electronics, design automation, cryo-CMOS, fabrication, and architectures. Submissions consist of a single abstract (maximum 1,500 characters); full papers are not requested. Authors of accepted abstracts will be offered oral, poster, or invited-talk slots and will join leading researchers from around the globe.
About QUEST
Welcome to QUEST, the workshop that refuses to stay in its lane! We’re all about breaking silos, mixing disciplines, and seeing what happens when researchers from superconducting electronics, cryo-CMOS, neuromorphic computing, quantum computing, VLSI design, and beyond collide in the best way possible.
At QUEST, we believe the most exciting ideas don’t come from staying inside your comfort zone. They happen when diverse expertise, fresh perspectives, and bold experimentation intersect. Whether you’re a seasoned expert, an ambitious newcomer, or just someone who loves exploring the unknown, this is the place to challenge assumptions, spark new collaborations, and rethink what’s possible.
QUEST × SSV 2025 Joint Sessions
To amplify cross-pollination even further, QUEST 2025 will merge its final half-day with the opening half-day of SSV 2025. This back-to-back joint session brings both communities into the same room—superconducting VLSI specialists and the wider QUEST crowd—so you can catch cutting-edge talks from both programs without changing venues or missing a beat. Stick around, dive in early, and experience two perspectives converging on one stage.

Joseph Bardin
Senior Staff Research Scientist, Google Quantum AI
Professor, University of Massachusetts Amherst
Joseph Bardin received the PhD degree in electrical engineering from the California Institute of Technology in 2009. In 2010, he joined the department of Electrical and Computer Engineering at the University of Massachusetts Amherst, where he is currently a Full Professor. His research group currently focuses on low temperature integrated circuits with applications in radio astronomy and the quantum information sciences. In 2017, he joined the Google AI Quantum team and, in addition to his university appointment, he currently leads Google’s efforts to develop electronics for their current and future quantum computers. Professor Bardin is a Fellow of the IEEE and was a recipient of a 2011 DARPA Young Faculty Award, a 2014 NSF CAREER Award, a 2015 Office of Naval Research YIP Award, a 2016 UMass Amherst College of Engineering Barbara H. and Joseph I. Goldstein Outstanding Junior Faculty Award, a 2016 UMass Amherst Award for Outstanding Accomplishments in Research and Creative Activity, a 2020 IEEE MTT-S Outstanding Young Engineer Award, and the 2022 IEEE MTT-S Microwave Magazine Best Paper Award.
Leonard Johnson
Senior Staff Member, MIT Lincoln Laboratory
Leonard Johnson is a senior staff member in the Quantum-Enabled Computation Group at MIT Lincoln Laboratory. He received his PhD in electrical engineering from the Massachusetts Institute of Technology in 1981, and then immediately joined MIT Lincoln Laboratory as a staff member. His research work has spanned microwave photonics, advanced wideband microwave receiver technologies, and superconductor electronics. He served in leadership roles in the IARPA Cryogenic Computing Complexity (C3) and SuperTools programs, including the development of the MIT Lincoln Laboratory superconductor electronics foundry. Most recently, he has been engaged in applying superconductor electronics to advance the state-of-the-art in digital signal processors.
Koji Inoue
Senior Vice President / Professor / Director of Quantum Computing System Center, Kyushu University
Koji Inoue is a professor in the Department of Advanced Information Technology at Kyushu University in Japan. He also hold titles as senior vice president, director of the Quantum Computing System Center (QCSC), and the director of the System LSI Research Center (SLRC) at Kyushu University. He has been serving as an organizing/program committee member of top-level international computer architecture conferences/symposiums, including ISCA, MICRO, ASPLOS, HPCA, and SC, and is now serving as an ACM SIGMICRO executive committee member. In 2018, he organized the IEEE/ACM MICRO held in Fukuoka, Japan, as a general co-chair. His expertise spans a broad range of topics in computer architecture for high-performance computing, low-power computing, IoT systems, superconductor computing, and quantum computing.
Tsuyoshi Yamamoto
Research Fellow, Secure System Platform Research Laboratories, NEC Corporation
Tsuyoshi Yamamoto received Ph.D. degree in applied physics from the University of Tokyo, Tokyo, Japan, in 2001. In 2001, he joined NEC Corporation, Tsukuba, Japan, where he has been engaged in research on superconducting quantum circuits. He is a project manager of Moonshot Research & Development program “Development of Integration Technologies for Superconducting Quantum Circuits” from the Japan Science and Technology Agency (JST).

Workshop Venue
Yokohama City Port Opening Memorial Hall
1-6, Honcho, Naka-ku, Yokohama, 231-0005
QUEST2025 will be hold at Yokohama City Port Opening Memorial Hall, also called as "Jack's Tower". It is a building in the neo-renaissance style that opened in 1917. The building is affectionately nicknamed "Jack". "Jack" is designated as a historical heritage building, and also currently serves as the Nakaku Ward Hall. The tip of the clock tower is lit with lights that over-pass the intersection. The lightshow on the red bricks takes you back in time to a different age - Yokohama in its golden era. The orange reflection from the lighting on the bricks is superbly beautiful, and is bound to make you smile. It is close to a Minatomirai Line station, making the building a good starting point for visiting Yokohama night views. Also nominated as a "Japan Heritage Night View".
