• Archer successfully demonstrated magnetic field measurement at cryogenic temperatures using its tunnel magnetoresistance (TMR) sensor technology
• This milestone bolsters quantum readout capabilities for its 12CQ project and noise characterisation in low temperature environments
• TMR sensors have the potential to be platform-agnostic, with possible use beyond Archer's quantum platform

Archer Materials Limited (ASX: AXE), a semiconductor company advancing quantum technology and medical diagnostics, has announced the successful demonstration of highly sensitive magnetic field measurements at cryogenic temperatures using its TMR sensors. The sensors were fabricated by Archer's foundry partner and integrated into a cryogenic-compatible test platform leveraging the company's in-house expertise in quantum technology, cryogenics, and semiconductor device integration. This milestone bolsters Archer's quantum readout capabilities for its 12CQ project and enables noise characterisation in low temperature environments. TMR sensors have the potential to be platform-agnostic, with possible use beyond Archer's quantum platform, as they are being developed to function at cryogenic temperatures, making them suitable for a range of quantum computing technologies, including superconducting, spin-based, and hybrid quantum systems. This creates opportunities for Archer to supply sensor technology more broadly across the quantum computing industry. The company is actively engaging with potential partners and customers to explore and validate bespoke TMR sensor applications, which could unlock commercial opportunities across quantum computing (including magnetic noise monitoring) and advanced sensing markets.

Archer is exploring strategic partnerships and customer engagements with the aim to address emerging markets in quantum instrumentation, cryogenic hardware systems, research and development tools for low-temperature physics, and custom sensor modules for space and defence applications.
