Japan recently launched its superconducting quantum computer built with homegrown components and software. The computer was launched at the University of Osaka’s Center for Quantum Information and Quantum Biology (QIQB).
This achievement signifies Japan’s technological prowess in quantum computing, demonstrating the nation’s capacity to design, manufacture, and integrate a complete quantum system.
Visitors attending the Expo 2025 in Osaka will get to interact with this cutting-edge technology through a dedicated exhibit.
How do quantum computers work?
Quantum computers operate in a completely different manner compared to classical computers. They utilize quantum bits, also known as qubits, which use quantum effects like superposition and entanglement. This lets them solve problems that normal computers can’t handle.
Quantum computers work in a completely different way from regular computers. Instead of using either 0 or 1 bits, they use qubits, thanks to quantum effects like superposition and entanglement. This lets them solve problems that normal computers can’t handle.
Reducing dependencies
The Osaka quantum computer project comprises key components that were developed in Japan. Everything has been manufactured in the country, from the dilution refrigerator that cools the qubits to temperatures near 10 millikelvin to the pulse tube refrigerator that plays a major role in initial cooling stages.
With this step, Japan has reduced its dependence on imported equipment, embracing self-reliance in the process. The project represents a sophisticated amalgamation of engineering disciplines, encompassing cryogenics, microfabrication, electronic control systems, and error-correcting algorithms, all harmonized within an integrated quantum computing architecture.
A robust software ecosystem
Alongside the advanced hardware, there’s also a powerful software system. Everything—from the user interface to the control systems—has been built as open-source tools, known as the Open Quantum Toolchain for Operators and Users (OQTOPUS).
This software makes programming, running, and monitoring the quantum computer easy, creating a user-friendly setup for researchers, developers, and enthusiasts. By keeping the software open-source and developed locally, the team in Osaka is promoting collaboration and ongoing improvements in quantum software.
Partners and exhibition
Distinguished institutions and industry leaders like RIKEN, ULVAC, Inc., ULVAC CRYOGENICS INC., e-trees.Japan, Inc., QuEL, Inc., QunaSys Inc., Systems Engineering Consultants Co., Ltd., TIS Inc., and Fujitsu Limited will be backing this project as partners. They have ensured technological self-reliance and created a vibrant ecosystem for quantum innovation within Japan.
The components of this quantum computer will be displayed at the Expo 2025 which will be held in Osaka, Japan, from 14th August to 20th August.
A promising future
Working with Professor Akihiro Kubota from Tama Art University, the exhibit will showcase art created by a quantum computer, blending science with creativity. This Expo aims to make quantum technology easier to understand and spark interest in the next generation of quantum innovators.
Quantum computers have the potential to resolve global challenges, ranging from new material development to optimization of complex systems for mitigating environmental impact.
They also promise to revolutionize everyday life through advancements in fields like machine learning. Japan has already demonstrated its ability to be a pioneer in this race with this project.
