Fujitsu and RIKEN created a powerful 256-qubit superconducting quantum computer at their joint research center. This machine builds on their earlier 64-qubit version from October 2023, using new high-density technology. The breakthrough helps make quantum computers more practical for solving complex world problems.

Both groups will add this quantum computer to their hybrid computing platform, which will be available worldwide starting early fiscal 2025. Growing from 64 to 256 qubits lets users tackle bigger challenges like analyzing larger molecules and testing advanced error correction methods. The team plans to improve how quantum and regular computers work together for better hybrid algorithms.

The new system solves technical issues through smart cooling inside the dilution refrigerator. It features a scalable 3D connection structure that arranges 4-qubit cells together, making it easier to increase qubit numbers without redesigning everything. The design fits four times more qubits in the same cooling unit as before.

Fujitsu aims to speed up practical quantum computing applications. They plan to build a 1,000-qubit computer at Fujitsu Technology Park in 2026. Both organizations extended their partnership until March 2029 to develop even larger quantum computers in the future.
