Fujitsu Limited and RIKEN have created a 256-qubit superconducting quantum computer. It’s one of the largest in the world. This big milestone happened at the RIKEN RQC-Fujitsu Collaboration Center. The two organizations set it up together in 2021.
This breakthrough builds on Japan’s second 64-qubit superconducting quantum computer, introduced in October 2023. Using new high-density packaging technology, the 256-qubit system boosts quantum computing power.
Starting in Q1 of fiscal year 2025, Fujitsu and RIKEN will offer the 256-qubit quantum computer to companies and research institutions via the Fujitsu Hybrid Quantum Computing Platform. This platform combines quantum and traditional computing. It allows for advanced hybrid algorithms that boost efficiency and enhance user experience.
The new system boosts computing power four times more than the old one. This lets users analyze bigger molecular structures and test complex error correction algorithms needing more qubit resources. Future updates to the hybrid platform will make it easier to connect quantum and classical systems. This will help run algorithms more effectively and practically.

Fujitsu and RIKEN plan to create superconducting quantum computers with over 1,000 qubits. They are working on improving qubit chip design and manufacturing. They also aim for better precision in quantum gate operations. The improved platform will be available to Japanese and global partners. These partners work together in areas like finance and drug discovery. This will help more people use quantum computing, both in hardware and software.
