Japan Adds a Second IQM Quantum Computer to Its Domestic Testbed

A Japanese measurement-solutions firm is buying a second superconducting quantum computer from Finland's IQM, pairing a 5-qubit training-and-benchmarking machine at its Tokyo R&D center with a 20-qubit research system at a government-industry lab outside the capital (Quantum Computing Report).

The new unit is IQM's 5-qubit Spark, sized for talent development, component benchmarking, and algorithm verification. It will sit at TOYO's R&D center in Kiba, Tokyo. The larger system, IQM's 20-qubit Radiance, was ordered earlier and is bound for AIST's G-QuAT facility in Tsukuba, a public-private research site that already runs hybrid compute, fabrication, and device-test services (Financial Post / Business Wire, AIST G-QuAT).

Both machines are scheduled for physical delivery by the end of 2026, with full operational status in early 2027. Through the dual setup, TOYO will open on-premises and cloud access to Japanese universities, startups, and industrial researchers (The Quantum Insider).

Japan's stated national quantum targets call for 10 million domestic users and ¥50 trillion (about $330 billion at recent rates) in quantum-related economic value by 2030. TOYO's purchase aligns with those policy goals, which are not measured results of this order. Neither machine is commercial scale: 5 qubits is training grade, 20 qubits is still research grade, and the access promise is forward-looking. IQM, recently listed on Nasdaq as IQMX, says its order backlog exceeds €102 million (about $110 million at recent rates) across 26 full-stack systems globally, with earlier deliveries in South Korea and Taiwan (Stock Titan / IQM).

Third-party validation of how many Japanese researchers and companies actually use the new TOYO machines is not yet available; the first real test comes when both systems go live in early 2027.
