Out of the lab and working in the foundries

At Diraq, we are engineers at heart. We turn the dazzle of quantum science into useful technology, with focus on practicality.

Solid IP foundations

Our engineers have been working on this technology for over two decades. We’ve patented our inventions along the way and now Diraq holds fundamental IP for the building blocks of a silicon CMOS quantum computer.

Diraq maintains over 60 patents and patent applications across major jurisdictions, including the US, Europe, Australia, China, Japan, South Korea and India. Our portfolio is highlighted by foundational IP in the design and operation of silicon spin qubits compatible with CMOS foundry manufacturing. We have patents covering a detailed CMOS-based architecture for billions of qubits, capable of full error correction, advanced methods for qubit control, quantum memory, as well as innovative CMOS device designs.

After filing, Diraq’s foundational IP has been validated through publication in leading, peer-reviewed Science- and Nature-group journals.
