Keysight Collaborates on Quantum Research in Japan

Keysight Technologies and Japan’s National Institute of Advanced Industrial Science and Technology (AIST) have recently entered into a Memorandum of Understanding (MoU) to foster collaboration in the realm of quantum research. The primary objective of this partnership is to advance the industrialization of computing and sensing technologies through joint efforts and expertise.

As per the terms of the agreement, Keysight and AIST will concentrate on delving into various aspects of quantum control technologies, low-temperature electronics device technology, modelling and simulation, and the standardization of these components in computing systems and sensing applications. This strategic collaboration aims to push the boundaries of quantum research and innovation.

The cornerstone of this partnership is the establishment of the Global Research Centre for Quantum-AI Fusion Technology Business Development (G-QuAT), which is set to house a cutting-edge 1000-qubit quantum computer. AIST, in collaboration with Yokohama National University, Tohoku University, and NEC, has developed a superconducting circuit capable of controlling multiple qubits at low temperatures.

In traditional quantum computers, the generation of microwave signals for qubit control typically takes place at room temperature, with individual transmission to qubits at low temperatures through separate cables. This setup results in a complex network of cables between room temperature and low temperature, limiting the controllability of qubits to around 1,000.

However, the innovative superconducting circuit enables the control of multiple qubits through a single cable using microwave multiplexing, as successfully demonstrated in proof-of-concept experiments at 4.2 K in liquid helium. This breakthrough has the potential to significantly increase the number of controllable qubits by enhancing the density of microwave signals per cable by approximately 1,000 times, thereby contributing to the advancement of large-scale quantum computers.

AIST is set to integrate and connect G-QuAT’s evaluation testbeds, device manufacturing capabilities, and computing infrastructure with Keysight's quantum control technologies and 5G / 6G evaluation technologies. This collaboration is poised to drive innovation and accelerate the development of quantum technologies for commercial applications.

Dr. Eric Holland, General Manager for Keysight’s Quantum Engineering Solutions group, emphasized the importance of sustained collaboration within the quantum community to propel quantum technology into the commercial realm. He expressed optimism about the partnership with AIST, stating that Keysight's expertise and solutions will play a pivotal role in advancing the quantum industry.

Furthermore, Holland highlighted Japan's ambitious 10-year plan to establish itself as a leader in quantum technology. He underscored the synergistic alignment between Keysight and Japan's quantum aspirations, emphasizing that the integration of Keysight's quantum control technologies with the G-QuAT facility will elevate it to a world-class quantum research center.
