Fujitsu Starts Development of its Superconducting Quantum Computer Targeting Completion in 2030
The Tech pioneers announced the launch of its official development program for a superconducting quantum computer with a scale surpassing 10,000 qubits, targeting completion in fiscal 2030. The project, partly under the NEDO “Research and Development Project of the Enhanced Infrastructures for Post-5G Information and Communication Systems,” will advance quantum computers toward industrialization in partnership with Japan’s National Institute of Advanced Industrial Science and Technology (AIST) and RIKEN. The collaborative project will continue until fiscal year 2027.
its next-generation quantum computer is designed to operate with 250 logical qubits and will leverage its innovative “STAR architecture,” developed for early-stage fault-tolerant quantum computing (early-FTQC). The focus is on enabling practical quantum computing—particularly for materials science, where complex simulations could yield groundbreaking discoveries. The company will concentrate on scaling technologies across multiple technical domains to achieve this goal.
Key Areas of Technology Development:
High-throughput, high-precision qubit manufacturing: Enhancing Josephson Junctions’ precision, which are core superconducting qubit components, to minimize frequency variations.
Chip-to-chip interconnect technology: Developing advanced wiring and packaging to link multiple qubit chips, supporting larger quantum processors.
High-density packaging and low-cost qubit control: Addressing cryogenic cooling and system control challenges with new approaches to reduce components and heat.
Decoding technology for quantum error correction: Creating algorithms and system designs for decoding measurement data and correcting errors in quantum computation.
Their selection for the NEDO project highlights its role in advancing quantum computing towards industrialization. The project will foster joint research with leading Japanese institutions and promote the application of quantum computing across new industries.
After delivering the 10,000-qubit system, They will pursue further advanced research, integrating superconducting and diamond spin-based qubits and targeting a 1,000 logical qubit quantum computer by fiscal 2035. The company also plans to explore architectures with multiple interconnected quantum bit chips.
Leadership Perspective
Vivek Mahajan, Corporate Executive Officer, Corporate Vice President, and CTO in charge of System Platform at Fujitsu Limited, said,
“Fujitsu is already recognized as a world leader in quantum computing across a broad spectrum, from software to hardware. This project, led by NEDO, will contribute significantly to its goal of further developing a Made-in-Japan fault tolerant superconducting quantum computer. We would also be aiming to combine superconducting quantum computing with diamond spin technology as part of our roadmap. By realizing 250 logical qubits in fiscal 2030 and 1,000 logical qubits in fiscal 2035, the Tech giant is committed to leading the path forward globally in the field of quantum computing. Additionally, they will be developing the next generation of its HPC platform, using its FUJITSU-MONAKA processor line, which will also power FugakuNEXT. They will further integrate its platforms for high-performance and quantum computing to offer a comprehensive computing platform to our customers.”
Background and Roadmap
The need for advanced computational power is increasing globally, driven by complex problems that traditional computers cannot solve. While a million-qubit, fully fault-tolerant quantum computer is a long-term goal, the Tech company is focused on delivering practical solutions in the nearer term.
Its commitment to quantum computing is shown through ongoing research and development. In August 2024, in collaboration with the University of Osaka, they introduced its STAR architecture—an efficient quantum architecture based on phase rotation gates. This innovation allows early-FTQC systems to outperform conventional computers using just 60,000 qubits. The RIKEN RQC-Fujitsu Collaboration Center, launched in 2021, has delivered a 64-qubit superconducting system in October 2023 and a 256-qubit world-leading system in April 2025.
The next challenge is scaling further while maintaining high fidelity across interconnected qubit chips and integrating more components within dilution refrigerators. Beyond superconducting technology, it is exploring diamond spin-based qubits with optical connectivity, in partnership with Delft University of Technology and QuTech, producing highly accurate and controllable qubits.
