Setting new standards with RF over fibre

Miraex’s quantum conversion platform turns ultra-low-noise transducers and entanglement into a distributed sensing capability — for precision navigation, geophysics, defence and critical-infrastructure monitoring.
The conversion platform

Beyond classical limits in remote sensing

Quantum properties of electromagnetic fields make it possible to break classical limits in many domains — especially remote sensing, where they sharply enhance sensitivity when detecting targets with very small radar cross-sections and weak returning echoes.
Highly efficient from a few MHz to over 100 GHz bandwidth
High-sensitivity microwave detection down to ~hundreds of photons with our SEOMs — single-photon detection is handed off to a downstream qubit, SPAD or SNSPD
Surpasses existing technology in sensitivity, EM immunity and compactness
Miniaturised devices → higher spatial resolution and integrated form factors
