Keysight Technologies has installed what they claim to be the world’s largest commercial quantum control system (QCS) at the National Institute of Advanced Industrial Science and Technology (AIST) in Tsukuba, Japan.
The system, now part of AIST’s Global Research and Development Centre for Business by Quantum-AI Technology (G-QuAT), supports over 1,000 qubits and is designed to enable large-scale quantum computing experiments.
“The 1,000-qubit control system developed here is the world’s first and largest of its kind. This system enables precise synchronisation, control, and readout of complex multi-channel signals, making large-scale qubit operations possible,” Masahiro Horibe, deputy director of G-QuAT, said.
The installation will improve AIST’s new testbed for next-generation quantum computers. Keysight said its flexible system design meets strict standards for controlling noise, timing and signal alignment, all of which are crucial for accurate quantum operations.
Claiming Keysight to be the first commercial vendor capable of such a QCS, Eric Holland, general manager of Keysight quantum engineer solutions, said, “Control systems serve a vital role in quantum computing, acting as the bridge between the classical and quantum worlds. This milestone is a key step toward achieving quantum advantage for practical business applications.”
The QCS integration is expected to support research on advanced quantum technologies and future commercial applications by enabling the precise management of large-scale qubit operations at G-QuAT.
Earlier this year, Keysight partnered with Samsung and NVIDIA to develop AI‑optimised RAN technology, aiming to enhance 5G and future 6G network performance. In April, the company also introduced its AI Data Centre Builder, a solution designed to support network architecture and host design for next-generation data centres.
In the same month, Keysight announced a strategic collaboration with SAMEER to drive innovation in 6G communications and healthcare technologies, further expanding its research footprint in India. The company also secured a NATO contract to enhance radar and electronic warfare capabilities, underscoring its role in advancing global defence technology, around the same time.
