Fujitsu has announced the start of research and development towards a superconducting quantum computer with a capacity exceeding 10,000 qubits, with construction slated for completion in fiscal 2030. This initiative is part of a project publicly solicited by NEDO (New Energy and Industrial Technology Development Organization), where Fujitsu will contribute to the thematic area of advancing the development of quantum computers toward industrialization. The project will be promoted through joint research with Japan’s National Institute of Advanced Industrial Science and Technology (AIST) and RIKEN and will run until fiscal year 2027.
The new superconducting quantum computer will utilize Fujitsu’s “STAR architecture,” an early-stage fault-tolerant quantum computing (early-FTQC) architecture. The company’s goals for logical qubit capacity are 250 logical qubits in fiscal 2030 and 1,000 logical qubits in fiscal 2035. Fujitsu’s research efforts will focus on developing scaling technologies in several areas: high-throughput, high-precision qubit manufacturing technology; chip-to-chip interconnect technology for creating larger quantum processors; high-density packaging and low-cost qubit control; and decoding technology for quantum error correction.
After building the 10,000+ qubit machine, Fujitsu plans to pursue research targeting the integration of superconducting and diamond spin-based qubits from fiscal 2030. The company will also be developing the next generation of its HPC platform, using its FUJITSU-MONAKA processor line, and plans to integrate its platforms for high-performance and quantum computing to offer a combined platform to customers. The STAR architecture, developed in collaboration with Osaka University, is designed to execute material energy estimation calculations with fewer qubits than conventional approaches.
This project is intended to contribute to the development of a Made-in-Japan fault-tolerant superconducting quantum computer, with a focus on delivering solutions in areas like materials science. The collaboration with AIST and RIKEN aligns with broader efforts to drive the development of industrialized quantum computing solutions. This initiative follows previous collaborations, including the delivery of a 64-qubit superconducting quantum computer in 2023 and a 256-qubit system in 2025 in collaboration with RIKEN.
