Keysight Delivers World’s Largest Commercial Quantum Control System to AIST’s G-QuAT Center, Advancing Quantum Computing Frontiers
In a groundbreaking development for the field of quantum computing, Keysight Technologies, Inc. (NYSE: KEYS) has successfully installed the world’s largest commercial quantum control system (QCS) at the National Institute of Advanced Industrial Science and Technology (AIST) in Japan. This state-of-the-art system, now integrated into AIST’s Global Research and Development Center for Business by Quantum-AI Technology (G-QuAT), supports over 1,000 qubits—a milestone achievement that sets a new benchmark for quantum computing infrastructure.
Quantum computers operate at the intersection of classical and quantum worlds, relying on sophisticated control systems to translate traditional programming and signals into the quantum realm of photons and qubits. As quantum computers scale in size, complexity, and performance, the demands on these control systems become increasingly stringent. Any compromise in precision or performance can significantly hinder the capabilities of the quantum computer. Recognizing this critical need, AIST turned to Keysight as its trusted partner to deliver a control system capable of meeting the rigorous requirements of next-generation quantum computing.
A Scalable Architecture for the Future of Quantum Computing
Keysight’s early investments in scalable architecture have paid off with this delivery, marking a pivotal moment in the evolution of quantum technology. The company’s quantum control system is engineered to maintain exacting standards of noise reduction, time alignment, and phase coherence across all channels—even as the number of qubits scales into the thousands. Extensive testing confirmed that the system meets or exceeds the demanding specifications required for large-scale quantum operations.
This installation positions Keysight as the first commercial vendor to deliver a quantum control system capable of supporting more than 1,000 qubits. It underscores the company’s ability to address the scaling challenges inherent in developing practical quantum computers. By enabling precise synchronization, control, and readout of complex multi-channel signals, Keysight’s QCS makes large-scale qubit operations possible, paving the way for advancements in quantum computing performance and applications.
A Groundbreaking Achievement for AIST’s G-QuAT Center
Dr. Masahiro Horibe, Deputy Director of G-QuAT at AIST, expressed his enthusiasm about the collaboration and the impact of this cutting-edge system: “The 1,000-qubit control system developed here is a groundbreaking device, the world’s first and largest of its kind, realized through Keysight’s exceptional engineering capabilities in response to our advanced technical requirements. Advancing quantum technology requires not only theoretical progress but also sophisticated engineering to support it. This system has enabled the precise synchronization, control, and readout of complex multi-channel signals, making large-scale qubit operations possible. It is a clear demonstration that engineering is paving the way for the future of quantum technology. We express our deep respect for Keysight’s development capabilities and look forward with great anticipation to further technological innovations.”
The integration of Keysight’s quantum control system into G-QuAT’s evaluation testbed represents a significant leap forward in quantum research. This testbed will serve as a platform for exploring the full potential of quantum computing, pushing the boundaries of scale and performance while fostering innovation in quantum algorithms, error correction, and practical business applications.
Bridging Classical and Quantum Worlds
Dr. Eric Holland, General Manager of Keysight Quantum Engineer Solutions, emphasized the critical role of control systems in advancing quantum computing: “Control systems serve a vital role in quantum computing, acting as the bidirectional bridge between the classical and quantum worlds. We are both honored and excited to partner with AIST G-QuAT, providing the hardware and software tools necessary to achieve the critical milestone of a 1,000-qubit quantum computer—a key step toward realizing quantum advantage for practical business applications.”
The ability to control and manipulate thousands of qubits simultaneously is no small feat. It requires not only cutting-edge hardware but also advanced software solutions capable of managing the immense complexity involved. Keysight’s quantum control system combines high-performance instrumentation with robust software tools, enabling researchers to orchestrate the delicate interactions required for large-scale quantum operations.
Unlocking Quantum Advantage for Real-World Applications
The deployment of this 1,000-qubit quantum control system marks a significant step toward achieving quantum advantage—the point at which quantum computers can solve problems faster or more efficiently than classical computers. This milestone opens the door to transformative applications across industries, including optimization, cryptography, materials science, and artificial intelligence. For example, businesses could leverage quantum computing to optimize supply chains, simulate molecular structures for drug discovery, or enhance machine learning models with unprecedented speed and accuracy.
As quantum technologies continue to mature, collaborations like the one between Keysight and AIST will play a crucial role in driving progress. By combining Keysight’s expertise in scalable quantum control systems with AIST’s leadership in quantum research, this partnership exemplifies how industry and academia can work together to overcome the challenges of building practical quantum computers.
