• Archer achieves key milestones on qubit demonstration
• Latest results leverage Archer's earlier EDMR breakthrough to progress toward operational qubits
• Successful wafer-scale synthesis of Archer's proprietary carbon material with long electron spin lifetimes

Archer Materials Limited (ASX: AXE), a quantum technology company, has made further progress in developing its carbon-based qubit technology, following its earlier milestone of achieving on-chip electrical detection of magnetic resonance (EDMR). The EDMR result showed that quantum spin states in Archer's carbon qubit material can be electrically detected on a chip, opening the way for smaller, more scalable devices that are easier to manufacture than traditional diamond-based optical systems. The latest engineering work has seen Archer complete several design and fabrication cycles to refine its gating and single-electron transistor (SET) architectures in carbon film, achieving reproducible device performance, which is critical for controlling charge and spin at the nanoscale and advancing toward operational qubits. Archer's collaboration with Queen Mary University of London is also progressing on spin state identification, with initial results showing gating on Archer's carbon films. Furthermore, Archer has successfully scaled the synthesis of its carbon-based quantum material to a 1-inch silicon wafer and achieved electron spin lifetimes exceeding 0.4 microseconds at room temperature, representing a major step toward practical scalability and CMOS-compatible integration. These achievements demonstrate Archer's clear and deliberate progression, with the EDMR breakthrough providing the foundation for spin detection, and the wafer-scale material growth, reproducible device engineering, and spin-state characterisation positioning the company to demonstrate functional qubits and high-performance quantum sensors.

Archer is positioned at the forefront of quantum computing and sensing innovation, supported by strategic collaborations and pursuing government-funding initiatives. The company is targeting qubit demonstration in mid-2026, which will be a significant technical milestone and deepen the scientific foundation for Archer's technology.
