Keysight Technologies delivers groundbreaking quantum control system to AIST

Keysight Technologies, Inc. has delivered a groundbreaking commercial quantum control system (QCS) to the National Institute of Advanced Industrial Science and Technology (AIST) in Japan. This state-of-the-art system has been integrated into the Global Research and Development Centre for Business by Quantum-AI Technology (G-QuAT).

The newly installed QCS will become a core component of G-QuAT's evaluation testbed, designed to push the limits of quantum computing in both scale and performance. In the realm of quantum technologies, a robust control system acts as a translator, bridging classical code and cabling with the quantum world of photons and qubits. As quantum machines continue to evolve in size and capability, their support systems must also rise to the new levels of precision and dependability.

Keysight’s investment in scalable architectures enabled the delivery of this control system, which supports leading-edge quantum computers. Rigorous testing assured its performance with high fidelity in noise management, time synchronisation, and phase alignment. This accomplishment crowns Keysight as the first commercial vendor capable of producing such scalable control systems for multi-qubit operations.

The QCS marks a milestone, capable of navigating 1,000+ qubit configurations, which is propelling the next phase in quantum computing.

Dr. Masahiro Horibe, Deputy Director of G-QuAT, AIST, said: “The 1,000-qubit control system developed here is a groundbreaking device, the world’s first and largest of its kind, realised through Keysight’s exceptional engineering capabilities in response to our advanced technical requirements. The advancement of quantum technology requires not only theoretical progress but also sophisticated engineering to support it. This system has enabled the precise synchronisation, 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.”

Dr. Eric Holland of Keysight emphasises their commitment to connecting the classical and quantum realms, assisting AIST in reaching the pivotal benchmark of a 1,000-qubit quantum computer. The continuously advancing quantum systems are sparking anticipation for practical applications across numerous industries.

Through their innovative engineering, Keysight ensures that the future of quantum technology is bright. With the strategic partnership in place, both companies look forward to uncharted technological territories, driven by an unwavering quest for excellence.
