Archer’s Qubit Breakthrough: EMDR Tech Advances Quantum Computing
▼ Summary
– Archer Materials achieved key milestones in qubit demonstration and made progress toward operational qubits in carbon-based materials.
– The company successfully scaled the synthesis of its proprietary carbon material to a 1-inch wafer with long electron spin lifetimes, enabling CMOS compatibility and scalability.
– Archer completed multiple design and fabrication cycles, achieving reproducible device performance in gating and single-electron transistor architectures.
– Collaborations, including with Queen Mary University of London, are advancing spin state identification and supporting the roadmap to a targeted qubit demonstration in mid-2026.
– These developments build on the earlier EDMR breakthrough, which enabled electrical detection of quantum spin states and integration with standard semiconductor fabrication methods.
Significant progress is being made in the development of scalable quantum computing technology, with Archer Materials achieving key engineering milestones on its path toward demonstrating a functional carbon-based qubit. The company has successfully advanced its proprietary platform by producing reproducible device performance in gating and single-electron transistor architectures, while also scaling up the synthesis of its unique carbon material across full silicon wafers. These accomplishments reinforce the practical viability of Archer’s approach and signal meaningful momentum ahead of its targeted qubit demonstration in mid-2026.
Following an earlier breakthrough in on-chip electrical detection of magnetic resonance, Archer has continued refining its device designs through multiple fabrication cycles. This iterative engineering work has yielded consistent and repeatable performance in nanoscale components, which is essential for precise control of electron charge and spin, the fundamental requirements for building operational qubits. The ability to reliably reproduce device behavior marks a critical step in transitioning from experimental research toward manufacturable quantum systems.
In parallel, collaborative research with Queen Mary University of London is advancing the identification and characterization of spin states within Archer’s carbon films. Early outcomes indicate successful gating operations, a vital capability for both controlling and reading out quantum information. Data anticipated later this year is expected to support further technical milestones and deepen the scientific understanding necessary to achieve a fully functional qubit.
Another major achievement involves the successful wafer-scale synthesis of Archer’s carbon quantum material, fabricated on one-inch silicon wafers while maintaining electron spin lifetimes exceeding 0.4 microseconds at room temperature. This development underscores the material’s uniformity and compatibility with conventional semiconductor manufacturing, opening a clear route to scalable production. Unlike many existing quantum platforms that require extreme cooling or complex optical setups, Archer’s carbon-film technology is designed to work under ambient conditions using standard CMOS processes.
These combined advances, spanning material synthesis, device reproducibility, and spin-state characterization, collectively strengthen Archer’s position in the emerging quantum technology sector. By establishing a carbon-based platform that aligns with existing semiconductor infrastructure, the company is addressing key bottlenecks in scalability and integration. This approach may eventually enable quantum devices to be incorporated directly into commercial electronic systems, supporting applications in computing, sensing, and medical diagnostics.
Dr. Simon Ruffell, CEO of Archer, emphasized the importance of these developments, noting that reproducible single-electron device performance and extended room-temperature spin lifetimes represent concrete progress toward practical quantum devices. With ongoing research and strategic collaborations, Archer continues to build a solid technical foundation aimed at delivering scalable quantum solutions for global markets.
