Fujitsu announced today that it has begun research and development on a superconducting quantum computer with a capacity exceeding 10,000 qubits. Construction is scheduled for completion in fiscal year 2030.
The new superconducting quantum computer will operate with 250 logic qubits and utilize Fujitsu's innovative "STAR architecture," an early-stage fault-tolerant quantum computing (early-FTQC) architecture also developed by the company. Fujitsu aims to make practical quantum computing possible, particularly in areas such as materials science, where complex simulations can unlock groundbreaking discoveries, and to this end, it will focus on advancing key technologies across various technical domains.
As part of this effort, Fujitsu has been selected as the implementing partner for the "Research and Development Project for Enhanced Infrastructure for Post-5G Information and Communication Systems" [1], publicly solicited by the New Energy and Industrial Technology Development Organization (NEDO). 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 the National Institute of Advanced Industrial Science and Technology (AIST) and RIKEN, and will run until fiscal year 2027.
Fujitsu is committed to driving the development of practical and industrialized quantum computing solutions. After this 10,000-qubit machine is built, Fujitsu will continue to pursue advanced research initiatives aimed at integrating superconductors and diamond-based spin qubits starting in fiscal year 2030, and has a 10,000-qubit logic machine planned for fiscal year 2035, while also considering the possibility of multiple interconnected quantum bit-chips.
