203010,000+ qubit system completion

Current obstacles

Cross-talk at scaleNeighboring qubits interact more as density increases, degrading gate fidelity.

Physics limits

Coherence timeSuperconducting qubits lose quantum information within microseconds.

How it works

2 parts

3D architecture

Four-qubit unit cells

Repeating 3D unit cells with four qubits enable modular scaling to larger arrays.

Cooling

Efficient dilution refrigerators

Improved design increases qubit density within existing refrigerators.

Fujitsu

Superconducting quantum, RIKEN collaboration, 256-1000 qubits

Fujitsu, a Japanese technology company, collaborates with Japan's RIKEN research institute to develop superconducting quantum computers. The partnership aims for practical quantum computing with scalable architectures.

Fujitsu is a major Japanese IT services and technology company publicly traded on the Tokyo Stock Exchange.
Its RIKEN collaboration has developed 64-qubit (2023) and 256-qubit (2025) superconducting systems.
The partnership plans a 1,000-qubit system for 2026 and 10,000+ qubits by 2030.
