• Achieved spin detection using resonant circuits, a key step toward qubit control
• Highlights unique spin properties of Archer's carbon-based quantum material
• Next stage is to demonstrate readout and control feasibility by Q4 2025

Archer Materials Limited (ASX: AXE) has announced a significant development in its 12CQ quantum computing project, demonstrating the ability to detect the spin of its proprietary carbon-based quantum material using a new resonator circuit design. This result is a key step toward achieving qubit control, a critical requirement for building a functional qubit for use in a quantum computer. Previous generations of superconducting resonators were unable to detect the spin of Archer's quantum material, but the company's interactive design optimization, simulation, and testing led to the new resonator circuit design that was able to clearly observe the strong coupling of spin states. This highlights the uniquely high spin density and significant spin lifetime of Archer's novel carbon-based spin material, which the company says opens the door to a range of exciting potential quantum applications beyond just qubits. The next stage of the 12CQ project will be to demonstrate the feasibility of readout and control by the end of 2025, followed by the development of a functional qubit targeted for the first half of 2026.
