Fujitsu and RIKEN unveil 256-qubit superconducting quantum computer
FujitsuSuperconducting Quantum Computer Roadmap
Fujitsu and RIKEN unveiled a 256-qubit superconducting quantum computer, a fourfold increase from their 64-qubit system. The new machine uses 3D scalable architecture with improved cooling efficiency and became available to global customers in fiscal 2025.
- 256 qubits: 4x increase from previous 64-qubit system
- 3D superconducting architecture with four-qubit unit cells
- Enhanced dilution refrigerator increases qubit density
- Hybrid quantum-classical computing platform
- Available to global customers in fiscal 2025
