Sydney-based quantum computing company Diraq has raised an additional AUD 10.5 million (USD 7 million) in an extended Series A-2 funding round led by Quantonation, with participation from Main Sequence and Taronga Ventures, among others. This adds to the USD 15 million raised in February 2024 , bringing the company's total Series A-2 funds to USD 22 million.

The funding will be used to develop Diraq's silicon "quantum dot" technology and roadmap to deliver a fault-tolerant quantum computer. Diraq aims to build quantum processors that can operate above absolute zero temperature.

Analyst QuickTake: Diraq has developed a method to precisely control single electrons in quantum dots to run logic gates. It recently achieved a 99.9% control accuracy for a quantum bit manufactured using industry-standard CMOS materials, demonstrating the potential for scalable manufacturing. Before Diraq, Quantinuum marked the first to demonstrate a 99.9% fidelity in April 2024 .
