Archer advances qubit development with EDMR breakthrough and scalability

Archer Materials Limited has achieved key milestones in its quantum technology development, progressing towards operational qubits in carbon-based materials. The company's latest engineering work builds on its earlier success in achieving on-chip electrical detection of magnetic resonance (EDMR), which provided a clear readout method for its qubits.

The company has completed multiple design and fabrication cycles, refining its gating and single-electron transistor architectures in carbon film, leading to reproducible device performance. Archer has scaled the synthesis of its proprietary carbon material to a 1-inch silicon wafer, achieving electron spin lifetimes exceeding 0.4 microseconds at room temperature. This demonstrates uniform material quality and potential for CMOS-compatible integration.

With these advancements, Archer aims for targeted qubit demonstration in mid-2026, supported by ongoing collaboration with Queen Mary University of London on spin state identification. These efforts reinforce Archer's position at the forefront of quantum computing and sensing innovation, working towards scalable quantum devices that operate at room temperature.
