Keysight Technologies, Inc. announced that its Quantum Control System (QCS) has been selected as the control system embedded within Fujitsu and RIKEN’s recently developed 256-qubit quantum computer at the RIKEN RQC-FUJITSU Collaboration Center in Japan, marking a pioneering step in the industry’s pursuit of fault tolerant quantum computer.

The integration of diverse specialized processors such as GPUs, TPUs, and now quantum processing units (QPUs), is crucial for the next era of advanced scientific computing and algorithmic exploration. Realizing the full potential of QPUs in hybrid computing environments necessitates significant progress in both qubit number and the reduction of error rates. Keysight’s involvement in this 256-qubit quantum computer positions the company to support Fujitsu and RIKEN in driving critical innovations in these key areas.

Quantum control systems are fundamental to the operation of any quantum computer. They serve as the interface between classical and quantum worlds, translating user commands into precise operations executed by the quantum processor. Simultaneously, they interpret the subtle changes in signals that reveal qubit state information. Keysight’s QCS was a natural fit for the RIKEN RQC-FUJITSU Collaboration Center due to its modularity, scalability, and market leading radio frequency (RF) performance. Since its introduction in February 2023, Keysight’s QCS has been adopted in academia, national laboratories, commercial companies, and innovative startups throughout the Americas, Europe, the Middle East, and the Asia Pacific region.

Dr. Eric T. Holland, General Manager Keysight Quantum Engineering Solutions, said: “Keysight is honored to be a part of this significant quantum journey beginning in Japan. Quantum computing is still a nascent technology, and the capabilities that Fujitsu, in collaboration with RIKEN, have brought to market are essential for enabling both quantum scientific discoveries as well as training the next generation of quantum scientists and engineers.”
