Keysight Technologies is contributing to solving the challenges of quantum computers by providing industry-leading quantum computer solutions: increasing the number of qubits and reducing error rates.


Keysight announced on the 4th that its Quantum Control System (QCS) has been adopted as the control system for a 256-qubit quantum computer developed at the RQC-Fujitsu Collaboration Center at the RIKEN Research Institute in Japan.

This adoption is seen as a major step forward in the development of error-tolerant quantum computers.

Quantum computing is emerging as an essential technology for next-generation scientific computing and algorithm development, following existing GPUs and TPUs.

In particular, increasing the number of qubits and reducing error rates are key tasks to fully realize the potential of quantum processing units (QPUs) in hybrid computing environments.

In this 256-qubit quantum computer project, Keysight is collaborating with Fujitsu and RIKEN to help solve these technical challenges.

Quantum control systems are an essential component of quantum computers, acting as an interface between classical computing and quantum processors.

It converts user commands into precise quantum operations and performs the function of analyzing qubit states to interpret signal changes.

Keysight's QCS is evaluated as a solution that meets the needs of Japanese laboratories with its modular structure, high expandability, and industry-leading RF performance.

Since its launch in February 2023, Keysight's QCS has been actively adopted by academia, national laboratories, private enterprises, and innovative startups across the U.S., Europe, the Middle East, and Asia Pacific.

“We are honored to participate in the quantum computing research underway in Japan,” said Dr. Eric T. Holland, general manager of Keysight’s Quantum Engineering Solutions business unit. “While quantum computing is still in its infancy, the work by Fujitsu and RIKEN will serve as an important foundation for nurturing the next generation of quantum scientists and engineers.”
