Japan has moved closer to becoming a global frontrunner in quantum computing as Hitachi, Intel K.K., and National Institute of Advanced Industrial Science and Technology (AIST) are set to conduct a government-funded research to develop next-generation quantum computing using silicon technology. The project is funded by Japan’s New Energy and Industrial Technology Development Organization (NEDO) with the objective of developing silicon-based technologies for future quantum computers and bridging the gap between laboratory research and commercial applications of quantum computing.
This is one of the several steps that Japan has been taking in order to become more self-sufficient in advanced computing, semiconductor chips, and artificial intelligence. This particular project, which will be ongoing until March 2029, is aimed at developing the core technologies for constructing scalable, fault-tolerant silicon-based quantum computers.
Accelerating the Industrialization of Quantum Computing
Unlike other quantum research efforts that concentrate only on experimental devices, Hitachi’s research effort concentrates on technology needs for commercialization.

The collaborating firms will work together to develop the design of silicon-based quantum chips comprising 100 qubits, semiconductor process technologies, package technologies, and cloud software development platforms, all of which would allow experimental quantum computers to be accessible by scientists and companies.
Silicon-based quantum computing is increasingly gaining interest because it can take advantage of existing semiconductor process technologies, thus being more scalable than some other types of quantum computers.
Four Strategic Development Areas
The research initiative is organized around four major technology pillars designed to support future large-scale quantum systems.
The first objective focuses on developing industrial-grade silicon quantum processors with approximately 100 qubits, incorporating improved chip architectures and cryogenic packaging technologies.
Second, the project will create a Process Design Kit (PDK) that provides standardized design rules and manufacturing information, enabling engineers to design silicon quantum chips compatible with commercial semiconductor fabrication processes.
Third, researchers will develop advanced 3D integration technologies capable of supporting future quantum systems with around 1,000 qubits, addressing the increasingly complex wiring and packaging challenges associated with larger processors.
Finally, Hitachi and AIST will establish a cloud platform through AIST’s Global Research and Development Center for Business by Quantum-AI Technology (G-QuAT), allowing researchers to remotely access experimental silicon quantum computing hardware and accelerate collaborative innovation.
Roadmap Toward Practical Quantum Systems
The collaboration outlines an ambitious long-term roadmap extending beyond the initial research period.
Hitachi will first roll out an initial cloud-based silicon quantum computing offering in the fiscal year 2027, followed by the development of a 100-qubit fault-tolerant quantum computing prototype through quantum error correction technology in the fiscal year 2028.
Ultimately, Hitachi and Tohoku University hope to build a 1,000-qubit prototype in the fiscal year 2030, establishing a stepping stone towards future fault-tolerant quantum computing machines capable of handling practical industry issues.
This serves as part of Japan’s overall plan to establish their place in quantum technologies.
Strengthening Japan’s Technology Industry
This is a huge step for Japan in terms of developing its state-of-the-art technological ecosystem.
Quantum computing will be the underlying technology for many industries such as pharmaceuticals, advanced materials, energy optimization, logistics, finance, and semiconductors. Through this technology investment in Japan, the country is capitalizing on its long-standing experience in the field of semiconductor production while generating new possibilities for the deep-tech industries.
This effort will also boost the demand for semiconductor production, cryogenics engineering, cloud computing, HPC, AI integration, and quantum software development.
Furthermore, this cooperation aligns with the plans of Japan to develop sovereign computing capabilities that will help Japan rely less on foreign quantum technologies.
Business Opportunities Across Industries
The commercialization of scalable quantum computing has the potential to transform numerous industries operating in Japan.
Pharmaceutical companies could accelerate drug discovery through advanced molecular simulations, while manufacturers may optimize materials development and product design. Logistics providers could solve highly complex routing and supply chain optimization problems, and energy companies could improve power grid management through advanced optimization algorithms.
Financial institutions are also expected to benefit from quantum-powered risk modeling, portfolio optimization, and fraud detection capabilities that exceed the performance of conventional computing systems.
Technology vendors, cloud service providers, semiconductor manufacturers, and systems integrators will find growing opportunities as enterprises begin preparing quantum-ready infrastructure and software environments.
Advancing Japan’s Leadership in Deep Technology
The partnership is based on the more extensive partnership agreement signed in early 2021 between Hitachi and Intel on quantum computing, semiconductor manufacturing, physical AI, and future digital infrastructure. Through combining the technological strengths of Hitachi and its knowledge of industrial and operational technology with the semiconductor manufacturing expertise of Intel, the two companies seek to make progress in implementing new computing technologies.
As regards Japan’s technology sector, this project that the government of Japan plans to undertake will serve as yet another landmark step in the overall innovative approach of the country. The development of quantum computing will provide Japan with an opportunity to be among the major centers for quantum technology in the world, while providing businesses engaged in AI, semiconductors, cloud computing, and advanced manufacturing with numerous business opportunities.
