Keysight Technologies, Inc. has delivered the world's largest commercial quantum control system (QCS) to the National Institute of Advanced Industrial Science and Technology (AIST) in Japan. The system has been integrated into the Global Research and Development Center for Business by Quantum-AI Technology (G-QuAT). This control system is now part of the new evaluation testbed at G-QuAT, which will push the limits of what is possible with quantum computing in terms of both scale and performance.

All quantum computers require a control system to translate from the classical world of code and cables to the quantum world of photons and qubits. As quantum computers grow in size, complexity, and performance, requirements for the control system become much more stringent. Any gap in the control system performance can compromise the capabilities of the quantum computer, so it was important for AIST to select the right partner for this critical component.

Keysight Technologies, Inc. announced that it helped AMD accelerate the testing of electrical compliance for PCI Express (PCIe) specification for pre-production AMD server CPUs. By providing early access to beta software, Keysight enabled AMD to develop and test a PCI Express technology-capable server motherboard operating at up to 64 GT/s. The server was shown for the first time at the PCI-SIG Developer's Conference June 11-12 in Santa Clara, CA.

PCIe 6.0 is the latest version of the high-speed interface that connects components inside servers and computers. With speeds of up to 256 GB/s using 16 lanes, PCIe 6.0 is designed to enable faster data transfer, lower latency, and better energy efficiency. These improvements make it a key enabler for the deployment of artificial intelligence (AI) technologies supporting the development of more advanced and efficient AI applications. The performance of PCIe 6.0 over PCIe 5.0 represents a significant improvement and a critical requirement for servers to easily interface with accelerator modules used in AI applications, as well as next-generation deployments of 802.3dj Ethernet communications.
