SEALSQ Corp acquired 100% of Swiss photonics pioneer Miraex SA using its $200 million Quantum Fund, deploying over $65 million to close the quantum interconnect layer of its sovereign vertical stack. It integrates compact radiation-tolerant TFLT photonic circuits to boost its QOSC initiative for LEO quantum key distribution and distributed sensing.
SEALSQ Corp completed the acquisition of 100% of Miraex SA, a Swiss developer of Thin Film Lithium Tantalate photonic integrated circuits for quantum interconnects. The transaction was funded by its $200 million Quantum Fund, with over $65 million deployed to secure the interconnect layer.
By integrating Miraex’s microwave-to-optical transduction and entanglement generation technologies, SEALSQ now commands a fully sovereign architecture spanning post-quantum silicon, photonic interconnects, and orbital infrastructure. This end-to-end stack underpins scalable distributed quantum computing, precision sensing, and entangled quantum networking.
Miraex’s compact, radiation-tolerant TFLT circuits are optimized for LEO deployment, enabling secure quantum key distribution and distributed sensing payloads across the QOSC constellation. This integration accelerates SEALSQ’s flagship Orbital Space Cloud program and enhances its space-grade quantum connectivity capabilities.
