Keysight Technologies, Inc. (NYSE: KEYS) has delivered a quantum control system (QCS) to the National Institute of Advanced Industrial Science and Technology (AIST) in Japan. The system has been integrated into AIST’s Global Research and Development Center for Business by Quantum-AI Technology (G-QuAT). This QCS is designed to support over 1,000 superconducting qubits, making it part of a new evaluation testbed at G-QuAT aimed at advancing the scale and performance of quantum computing.
The delivered QCS is intended to translate classical code into quantum operations, a function that becomes more complex as quantum computers grow in size. Extensive testing indicated that requirements for noise, time alignment, and phase coherence are maintained across the system. This capability enables the precise synchronization, control, and readout of complex multi-channel signals, facilitating large-scale qubit operations. Keysight is positioned as the first commercial control system vendor to deliver a system supporting over 1,000 superconducting qubits.
This QCS is now a component of G-QuAT’s new evaluation testbed, which aims to advance the scale and performance of quantum computing. Dr. Masahiro Horibe, Deputy Director of G-QuAT, AIST, highlighted the system’s role in supporting quantum technology advancement through its engineering capabilities. Dr. Eric Holland, General Manager, Keysight Quantum Engineer Solutions, noted the function of control systems as a bridge between classical and quantum domains, contributing to achieving milestones in quantum computing. This delivery expands on previous collaborations between Keysight and AIST for quantum research.
