Record Accuracy Achieved by Standard CMOS Quantum Computing Device

Diraq, a quantum computing company, has made a significant advancement in the field by confirming a remarkable 99.9% single qubit control fidelity. This achievement propels Diraq to the level of precision necessary for the development of powerful, full-scale, error-corrected quantum computing processors that can be manufactured by existing silicon chip foundries.

Andrew Dzurak, the CEO and Founder of Diraq, expressed his excitement about the breakthrough, stating, “The record demonstration was achieved using a qubit device manufactured by imec, the world's leading independent nanoelectronics R&D hub based in Leuven, Belgium. This partnership with imec is crucial for Diraq's technology roadmap as we aim to realize a fully error-corrected quantum computing system ahead of our competitors."

The achievement, showcased on the imec device, represents the highest single qubit fidelity demonstrated to date for a silicon spin qubit produced in a 300mm foundry environment using standard CMOS materials and processes. This milestone was made possible by Diraq's sophisticated qubit control and measurement techniques developed over the past decade.

Diraq, known for its expertise in quantum control and processor design, is working on integrating qubits with standard CMOS transistors that are fundamental to today's IT industry. By designing chips that will be manufactured by GlobalFoundries this year, Diraq aims to integrate silicon qubit devices with standard transistors, a combination that will significantly increase qubit numbers on a chip.

"Commercially viable quantum computing capable of revolutionary applications must employ quantum error correction processes that will require many millions of qubits," Dzurak emphasized. "Our roadmap leverages existing semiconductor foundry capabilities to develop quantum processor chips on a scale that can support the design of targeted pharmaceuticals and advanced materials."
