Fujitsu and RIKEN develop world-leading 256-qubit superconducting quantum computer

Fujitsu Limited and RIKEN today announced the development of a world-leading 256-qubit superconducting quantum computer, established at the RIKEN RQC-FUJITSU Collaboration Center. This new quantum computer builds upon the advanced technology of the 64-qubit iteration, launched with the support of the Japanese Ministry of Education, Culture, Sports, Science and Technology (MEXT) in October 2023, and incorporates newly-developed high-density implementation techniques. This announcement marks another crucial step toward the practical application of superconducting quantum computers and unlocking their potential to grapple with some of the world’s most complex issues.

Both organizations will integrate the 256-qubit superconducting quantum computer into its platform for hybrid quantum computing lineup and offer it to companies and research institutions globally starting in the first quarter of fiscal 2025. The platform’s expansion from 64 to 256 qubits empowers users to tackle more complex challenges, including the analysis of larger molecules and the implementation and demonstration of sophisticated error correction algorithms.

Moving forward, both organizations will further enhance the platform’s usability by working to enable seamless collaboration between quantum and classical computers, enabling the efficient execution of hybrid quantum-classical algorithms.

Fujitsu and RIKEN will continue R&D efforts toward the launch of a 1,000-qubit computer, which is scheduled to be installed in a new building at Fujitsu Technology Park in 2026.

Fujitsu and Osaka University accelerate progress toward practical quantum computing

Fujitsu Limited and the Center for Quantum Information and Quantum Biology at Osaka University (QIQB) today announced the joint development of two new technologies for the space-time efficient analog rotation quantum computing architecture [1] that will accelerate the realization of practical quantum computing.

Fujitsu and QIQB have leveraged these new technologies, one that improves phase angle accuracy during phase rotation [2] and one that automatically generates efficient qubit operation procedures, to show that it is theoretically possible for a quantum computer to perform a calculation that would take a classical computer five years, in only ten hours. The two organizations found that the calculation, a material energy estimate, would be possible using only 60,000 qubits, significantly less than the amount typically thought to be required (3) for fault-tolerant quantum computation (FTQC) to surpass the calculation speed of classical computers.


[1] Space-time efficient analog rotation quantum computing architecture :
A quantum computing architecture that can significantly reduce the number of physical qubits needed for arbitrary phase rotation, An essential step in achieving practical quantum computing.
