Keysight Technologies, Inc., a leading provider of advanced design and validation solutions, has installed the world’s largest commercial quantum control system at Japan’s National Institute of Advanced Industrial Science and Technology (AIST). The system is now operational at G‑QuAT, AIST’s Global Research and Development Center for Business by Quantum‑AI Technology, and supports over 1,000 superconducting qubits — a milestone in the evolution of scalable quantum computing infrastructure.
As quantum computing systems expand, the complexity and precision required of control systems increases dramatically. Keysight’s newly deployed solution meets these demands by ensuring ultra-low noise, phase coherence, and tight time alignment across hundreds of channels, enabling large-scale, high-fidelity quantum operations critical for meaningful quantum computation.
Dr. Masahiro Horibe, Deputy Director of G-QuAT, praised the deployment, stating, “This system is a groundbreaking device, the world’s first and largest of its kind. Keysight has delivered a solution that precisely meets the demanding technical needs of our quantum computing efforts.”
The collaboration between Keysight and AIST began in 2024 through a memorandum of understanding focused on advancing hybrid quantum-AI computing and commercializing next-generation control systems. This installation is the first of its scale, positioning Keysight as the only commercial vendor to have delivered a system capable of supporting over 1,000 qubits.
Dr. Eric Holland, General Manager of Keysight’s Quantum Engineering Solutions, added, “Control systems serve a vital role in quantum computing, acting as the bidirectional bridge between the classical and quantum worlds. We are honored and excited to support AIST G‑QuAT in achieving the milestone of a 1,000‑qubit quantum computer.”
The G-QuAT Center is central to Japan’s broader national strategy to lead in quantum-AI fusion technologies, and the deployment of this system represents a key advancement in building the necessary infrastructure for scalable quantum computing applications in science, industry, and defense.
