Fujitsu outlines path to 10,000+ qubits and quantum error correction by 2030

Fujitsu/Superconducting Quantum Computer Roadmap

Fujitsu formally launched development of a 10,000+ qubit superconducting system targeting fiscal 2030 completion. The STAR (early-stage fault-tolerant quantum computing) architecture aims to extract ~250 logical, error-corrected qubits from the physical ensemble—a critical step toward practical applications.

• 10,000+ physical qubits planned for fiscal 2030 completion
• 250 logical qubits as the first milestone within STAR architecture
• Collaboration with NEDO, AIST and RIKEN on scaling technologies
• Focus on chip-to-chip interconnects and quantum error correction decoding
• Roadmap extends to 1,000 logical qubits by 2035 using hybrid superconducting and diamond-spin systems
