Fujitsu and RIKEN companies have unveiled a 256-cubit superconducting quantum computer at the RIKEN RQC-FUJITSU Collaboration Center in Japan, achieving an increase in technological capability over its previous version.

This new system was built on the basis of an existing 64-cubit unit, reusing the unit cell design and reorganizing it into a three-dimensional structure. Such architecture allows scaling the number of cubits without extra modifications of the whole system, enabling solutions to more complex problems such as molecular simulations and error correction algorithms.

After finding the precise thermal balance, it is possible to maintain the ultra-low temperatures needed to operate with stability, without altering performance or redesigning the cooling system.
The 256-cubit computer will be integrated into Fujitsu’s hybrid quantum computing platform, which enables it to run quantum-classical algorithms. This platform will be available to global institutions and enterprises from the first fiscal quarter of 2025.
Going forward, Fujitsu and RIKEN plan to develop a 1,000-cubit system by 2026 as part of their expansion plans at the Fujitsu Technology Park. They will also extend the operation of their Collaboration Center through 2029, with a focus on continuing research into more advanced quantum systems systems and on seamlessly integrating software and hardware.
