G-QuAT & Keysight drive Japan’s Quantum Computing revolution
G-QuAT
The largest commercial quantum control system in the world, installed by Keysight at AIST in Japan, allows over 1,000 qubit operations.
Keysight Technologies, Inc. built and implemented the world's largest commercial quantum control system (QCS) at Japan's National Institute of Advanced Industrial Science and Technology (AIST). Quantum-AI Technology integrates this groundbreaking system into AIST's Global Research and Development Centre for Business. Japan is leading quantum technology advancement, which will enable large-scale quantum computer systems.
New Quantum Computing Scale and Performance Era
The freshly installed QCS is key to a new G-QuAT evaluation testbed that will hold over 1,000 superconducting qubits. This testbed enhances quantum computing performance and scale. Keysight, the first commercial control system vendor, can support over 1,000 superconducting qubits. Keysight's QCS can scale for upcoming quantum computers.
All quantum computers need a control mechanism to switch from cables and code to photons and qubits. Quantum operations needed for qubit manipulation are translated from conventional instructions. As quantum computers grow in size, complexity, and performance, these control systems must meet more stringent requirements. To maintain quantum computation integrity, any control system performance lapse can severely limit the quantum computer's capabilities. This critical requirement required AIST to find a highly qualified partner.
Because Keysight invested early in scalable architecture, it could build such a massive system. The system has met noise, time alignment, and phase coherence standards through extensive testing. Large-scale qubit operations depend on this trustworthy capability to properly synchronise, control, and readout complex multi-channel signals.
Industry Leaders Applaud Engineering Advancement
The system revolutionised quantum technology, according to AIST's G-QuAT Deputy Director Dr. Masahiro Horibe. He said: “The 1,000-qubit control system developed here is a groundbreaking device, the world's first and largest”. Dr. Horibe said Keysight's extraordinary engineering capabilities in response to complex technical needs made this historic achievement possible. He said “the advancement of quantum technology requires not only theoretical progress but also sophisticated engineering to support it”.
He said quantum technology's future is being prepared by engineering's flawless synchronisation, control, and readout of complex multi-channel signals for large-scale qubit activities. Dr. Horibe admired Keysight's development capabilities and predicted technological advances.
Control systems are vital in quantum environments, according to Keysight Quantum Engineer Solutions general manager Dr. Eric Holland. As the bidirectional bridge between the classical and quantum worlds, control systems are crucial to quantum computing, said Dr. Holland. He added that “reaching the 1,000-qubit milestone is a significant step towards realising quantum advantage in practical applications”. Dr. Holland said Keysight is “proud and honoured to partner with AIST G-QuAT, offering the hardware and software tools required to achieve this important milestone.” This release builds on Keysight and AIST's quantum research collaboration.
Japan's Global Quantum Race Strategy
This cutting-edge QCS is crucial to Japan's quantum computing efforts. By attracting cutting-edge computer technology collaborations, it boosts the country's global quantum leadership. Japan, the US, China, and the EU are investing more in quantum research. Quantum computing discoveries could alter many industries, therefore governments and businesses worldwide are competing for them. This AIST G-QuAT centre display impressively illustrates quantum technology's future engineering.
