Background
On July 22, 2026, Hitachi, in collaboration with Intel’s Japan subsidiary and the National Institute of Advanced Industrial Science and Technology (AIST), announced the launch of a significant government-backed initiative. Selected by Japan’s New Energy and Industrial Technology Development Organization (NEDO), this project is set to develop and prototype quantum processors utilizing Intel’s cutting-edge 1.8nm ‘Intel 18A’ process technology. This national effort underscores Japan’s strategic push to establish a leading position in the global quantum computing landscape, aiming for a 50-qubit silicon quantum computer prototype by the end of fiscal year 2028 and a 1,000-qubit 3D integrated silicon quantum processing platform by the end of fiscal year 2030.
Key Findings
The collaborative project, spearheaded by Hitachi, Intel Japan, and AIST under NEDO’s aegis, is focused on developing silicon-spin quantum chips leveraging Intel’s advanced 1.8nm ‘Intel 18A’ process. Key targets include the realization of a 50-qubit class silicon quantum computer prototype by the close of fiscal year 2028, followed by a 1,000-qubit 3D integrated silicon quantum processing platform by the end of fiscal year 2030. This initiative is pivotal for advancing Japan’s technological leadership and international competitiveness in the burgeoning field of quantum computing.
Technical and Development Details
- Intel 18A Process Technology: At the heart of this project lies Intel’s leading-edge 1.8nm process technology, ‘Intel 18A.’ This extreme miniaturization is crucial for achieving higher transistor density and superior performance, directly translating to enhanced integration density and stability for silicon qubits. Silicon-spin qubits, specifically, are favored for their compatibility with established semiconductor manufacturing processes, offering a promising pathway towards scalable quantum chip fabrication.
- Qubit Count Targets: The project’s phased approach targets a 50-qubit class system by the end of fiscal year 2028. This initial milestone operates within the current Noisy Intermediate-Scale Quantum (NISQ) era, where such systems are anticipated to address specific optimization problems and simulations beyond the reach of classical supercomputers. The more ambitious goal of a 1,000-qubit 3D integrated platform by the end of fiscal year 2030 represents a significant stride towards the realization of Fault-Tolerant Quantum Computers (FTQC). 3D integration technology is paramount for optimizing inter-qubit connectivity and efficiently routing control signals, thereby managing the increasing complexity inherent in large-scale quantum systems.
- Research Framework: This tripartite collaboration leverages distinct strengths. Hitachi contributes its extensive R&D experience in semiconductors and quantum devices. Intel Japan provides specialized expertise in advanced process technology and manufacturing know-how. AIST acts as a vital nexus, bridging fundamental quantum research with practical industrial applications. This synergistic industry-academia-government model is designed to accelerate R&D cycles and expedite the transition of quantum innovations from laboratory to market.
The project is specifically tasked with overcoming critical challenges in silicon quantum computer development, including extending qubit coherence times, minimizing error rates, and developing high-precision qubit control technologies.
Industry Context and National Strategy
Quantum computing stands poised to revolutionize fields ranging from drug discovery and materials science to financial modeling and artificial intelligence. Acknowledging this transformative potential, nations globally, including the United States and China, are investing heavily to secure leadership in this strategic domain. The Japanese government has formally recognized quantum technology as a national priority, outlining its vision in the ‘Quantum Future Industry Creation Strategy’ and the ‘Quantum Technology Innovation Strategy.’ These initiatives vigorously promote both R&D and the industrial application of quantum technologies. NEDO’s grant program serves as a critical mechanism to operationalize this national strategy, ensuring Japan’s industrial sector can maintain and enhance its international competitiveness. The integration of state-of-the-art process technology, such as Intel 18A, is deemed immensely significant for accelerating Japan’s quantum technology advancements.
Strategic Significance and Outlook
The collaborative project involving Hitachi, Intel, and AIST is poised to significantly accelerate the practical application of silicon quantum computing technology. The envisioned 50-qubit class prototype will facilitate the exploration of practical quantum applications within a constrained scope, providing invaluable insights. The subsequent 1,000-qubit platform, however, promises to unlock solutions for more complex problems, effectively laying crucial groundwork for the advent of fault-tolerant quantum computers. Successful execution of this initiative is expected to bolster Japan’s nascent quantum technology ecosystem, stimulate further collaboration with both domestic and international partners, and ultimately drive the creation of new industries and foster economic growth. More broadly, it will firmly establish Japan’s position as a leading contender in the intensely competitive global race for quantum technological supremacy.
