Archer Materials Advances Carbon Qubit Tech with Wafer-Scale Breakthrough
Archer Materials has achieved critical milestones in its carbon-based quantum technology, including wafer-scale synthesis and reproducible device performance, setting the stage for operational qubits by mid-2026.
- Reproducible device performance in gating and single-electron transistor architectures
- Successful wafer-scale synthesis of proprietary carbon quantum material
- Electron spin lifetimes exceeding 0.4 microseconds at room temperature
- Collaboration with Queen Mary University advancing spin state identification
- Targeted qubit demonstration planned for mid-2026
Building on a Quantum Breakthrough
Archer Materials, an Australian quantum technology innovator, has reported significant progress in developing its carbon-based qubit platform. Following its earlier success in achieving on-chip electrical detection of magnetic resonance (EDMR), the company has now refined device architectures and scaled its proprietary carbon material to wafer level. These advances mark important steps toward practical quantum computing devices that can operate at room temperature.
From Lab to Wafer-Scale Production
Central to Archer’s progress is the successful synthesis of its carbon quantum material on a 1-inch silicon wafer. This wafer-scale production not only demonstrates uniform material quality but also confirms compatibility with standard semiconductor manufacturing processes, known as CMOS technology. Achieving electron spin lifetimes exceeding 0.4 microseconds at room temperature further underscores the material’s potential for scalable quantum devices.
Engineering Reproducibility and Collaboration
Archer has completed multiple design and fabrication cycles to deliver reproducible performance in gating and single-electron transistor (SET) device architectures. This reproducibility is critical for controlling quantum charge and spin states, which underpin qubit operation. Meanwhile, collaboration with Queen Mary University of London is advancing spin state identification, a key milestone for confirming the quantum behaviour necessary for functional qubits.
Positioning for Commercial Quantum Devices
These technical achievements collectively position Archer to demonstrate operational qubits by mid-2026. The company’s carbon-film platform offers advantages over existing quantum technologies, such as diamond-based systems, by enabling smaller, more scalable devices that integrate seamlessly with existing semiconductor chips. Archer’s CEO, Dr Simon Ruffell, emphasises that this progress strengthens the company’s pathway toward commercial quantum technologies that are simpler and more integrated.
Looking Ahead
As Archer continues to advance its roadmap, upcoming data releases and technical milestones will be closely watched by investors and industry observers. The company’s ability to scale quantum materials and demonstrate reproducible device performance at room temperature could be a game-changer in the competitive quantum computing landscape.
Bottom Line?
Archer’s wafer-scale quantum material and reproducible devices set the stage for a pivotal 2026 qubit demonstration.
Questions in the middle?
- Will Archer’s carbon-based qubits outperform existing diamond and superconducting platforms in commercial applications?
- How will Archer’s collaborations and government funding initiatives accelerate its path to market?
- What are the next technical challenges Archer must overcome to achieve full qubit operation and integration?
