Keysight Technologies has announced that its Quantum Control System (QCS) is embedded in the newly launched 256-qubit superconducting quantum computer developed by Fujitsu and RIKEN. The system, located at the RIKEN RQC-FUJITSU Collaboration Center in Japan, marks a significant milestone toward scalable, fault-tolerant quantum computation. As a modular and scalable platform, QCS enables both quantum-to-classical and classical-to-quantum conversions essential for high-fidelity quantum operations.
The Fujitsu–RIKEN system is part of Japan’s broader quantum computing initiative and demonstrates how large-scale quantum processors will integrate with hybrid high-performance computing architectures, including GPUs and TPUs. Keysight’s QCS was selected for its RF performance and support for complex, precision control required by large-scale superconducting qubit systems. The QCS platform has already been adopted by research institutions, startups, and national labs across global regions since its 2023 release.
Keysight’s role underscores the importance of robust control infrastructure in advancing both research and workforce training. According to Dr. Eric Holland, General Manager of Keysight Quantum Engineering Solutions, “Quantum control is the bridge between classical instruction and quantum logic.”
