Step-change advance in Archer’s 12CQ chip development with quantum information detected in its qubit material at room temperature using CMOS technology.

CMOS is a widely used semiconductor technology for building the chips found in most modern-day devices.
Integrating Archer’s 12CQ qubit material with CMOS technology provides a potential pathway for the development of practical quantum-enabled mobile devices.

Archer is the only ASX listed company and one of a few players in the world developing qubit processor technology.
CMOS is the predominant technology used in designing chips in the semiconductor industry and it is broadly used today to form integrated circuits in numerous and varied applications. Processors, memory, and sensors are among many electronic devices that make use of this technology.  The use of CMOS technology in the semiconductor industry is expected to continue in the long-term therefore, it is important to demonstrate the functional incorporation of the 12CQ qubit material with CMOS devices.

In a major technological feat, Archer has now used a single-chip integrated electron spin resonance detector based on CMOS technology to detect the quantum spin states in the as-prepared 12CQ qubit material in a controlled atmosphere at room temperature. The quantum states were found to be sufficiently well preserved when operating in the on-chip environment.

Commenting on the 12CQ chip progress, Archer CEO Dr Mohammad Choucair said: “The significance of the work to realise a CMOS chip that successfully detects the quantum spin states in our qubit material at room temperature cannot be understated and represents a step-change technological achievement in advancing Archer’s 12CQ quantum chip development.

“A key advantage of the new CMOS chip is that the componentry is made using standard and commercially available semiconductor fabrication technology.

“This achievement builds on the considerable progress Archer has made this year in the design and development of the 12CQ chip, which all link to the future operation of the technology.”
