Fujitsu Quantum computers With 10000+ superconducting Qubits
Fujitsu quantum computers
Fujitsu wants a 10,000-qubit superconducting quantum computer by 2030.
By fiscal 2030, Fujitsu plans to construct a superconducting quantum computer with over 10,000 qubits. Complex simulations are essential to innovative materials science discoveries, and this key effort could hasten quantum technology deployment.
STAR Architecture underpins fault-tolerant quantum computing
Fujitsu's objective centres on their groundbreaking "STAR architecture," an early-FTQC design. This phase rotation gate-based design, presented in August 2024 in conjunction with the University of Osaka, aims to enable early-FTQC systems that outperform classical computers with a qubit target of under 60,000. Fujitsu proposes to deploy the STAR architecture and 250 logical qubits in the 2030 machine for practical quantum computing.
Vivek Mahajan, CTO in charge of System Platform, Corporate Executive Officer, and Corporate Vice President at Fujitsu Limited, said, “Fujitsu is already recognised as a world leader in quantum computing across a broad spectrum, from software to hardware.” He stated that the NEDO-led project will help Fujitsu create a fault-tolerant superconducting quantum computer made in Japan.
Comprehensive Plan for Advanced Quantum System Development
Fujitsu's commitment exceeds 2030. After building the 10,000-qubit machine, the corporation will perform advanced research on superconducting and diamond spin-based qubits in fiscal 2030. This long-term goal is to create a 1,000-logical qubit machine by fiscal 2035 using interconnected quantum bit-chips.
Its hardware division is progressing well. Established in 2021 with RIKEN, the RIKEN RQC-Fujitsu Collaboration Centre built a 64-qubit superconducting quantum computer in October 2023 and a world-class 256-qubit system in April 2025. This relationship and cooperative research with Japan's National Institute of Advanced Industrial Science and Technology boost Fujitsu's R&D. Fujitsu is studying diamond spin-based qubits, which use light for connectivity, with QuTech and Delft University of Technology in addition to superconducting technology. Highly accurate and controlled qubits were developed by this research.
Targeted Technology Development Fixes Scaling Issues
Scaling quantum computers to larger systems requires overcoming many complex challenges. Fujitsu's research aims to enhance scaling technologies in various technical sectors. Important areas include:
High-throughput, high-precision qubit production technology: This reduces frequency variations by improving Josephson Junction manufacturing precision, which is vital to superconducting qubits. Chip-to-chip interconnect technology: To make larger quantum processors, sophisticated wiring and packaging technologies must connect several qubit devices. High-density packing and cheap qubit control: This field addresses cryogenic cooling and control issues such reducing dilution freezer components and heat dissipation. Decoding technology for quantum error correction: Robust operation requires algorithms and system designs to decode measurement data and rectify quantum computation errors. Scaling technology issues include maintaining high fidelity over many interconnected qubit devices and improving dilution refrigerator component and wiring integration.
Market positioning and investment strategy
Fujitsu's quantum computing investment could pay out financially. In addition to financial support, NEDO's help and cooperation with other research institutes alleviate some of the risks associated with key research and development activities. Analysts warn that investors should recognise that this investment is long-term since financial advantages may not be fully realised until the technology is fully developed and brought to market.
Fujitsu's focus on quantum computing aligns with the market's demand for advanced computational solutions in several industries. Fujitsu may lead quantum computing due of its potential applications in materials research and other fields. Other internet firms investing extensively in quantum technology will challenge the company. Fujitsu's success hinges on industry-specific, scalable solutions.
Fujitsu's FUJITSU-MONAKA CPU family will power FugakuNEXT, its next-generation HPC platform. The company wants to integrate its high-performance and quantum computing systems to offer a full computing platform. Although a fully fault-tolerant quantum computer with one million qubits is the goal, Fujitsu is dedicated to providing realistic solutions in the near future.
