SEALSQ Integrates Miraex to Bolster Quantum Capabilities

SEALSQ finalized its total acquisition of Miraex SA on June 2, 2026, gaining full control of the Swiss photonics innovator. Funding came from the company’s specially established $200 million Quantum Fund, designed specifically for strategic investments throughout emerging quantum sectors. Operating from Switzerland’s EPFL Innovation Park in Ecublens, Miraex now serves as SEALSQ’s dedicated quantum photonics division.

SEALSQ has allocated over $65 million from the Quantum Fund toward strategic quantum initiatives, technology acquisitions, and infrastructure development internationally. Miraex brings a sophisticated photonic interconnection system enabling quantum processors to interface seamlessly with extended optical transmission networks. This integration advances SEALSQ’s vision of delivering a complete sovereign technology stack encompassing processors, cryptographic systems, network architecture, computational resources, communication channels, and digital platforms.

SEALSQ maintains existing operations in secure semiconductor manufacturing, quantum-resistant cryptographic solutions, trusted computing frameworks, and quantum network technologies serving enterprise and governmental sectors. The Miraex acquisition provides critical interconnection infrastructure necessary for transmitting quantum data among distributed processors, facilities, orbital assets, and communication channels with enhanced security. Consequently, this expansion reinforces SEALSQ’s market presence throughout cybersecurity, telecommunications, cloud services, defense contracting, infrastructure protection, and secure satellite communications.

Market Entry Spans Four Strategic Quantum Sectors

Miraex engineered a Thin Film Lithium Tantalate Photonic Integrated Circuit solution enabling quantum signal transformation and dependable system integration. The technology translates data between processor microwave frequencies and optical wavelengths utilized throughout protected communication infrastructures and satellite connections. This translation capability enables modular quantum architectures, allowing independent processors to aggregate computational power through secure, efficient, and expandable photonic links across geographic distances.

SEALSQ intends to address distributed quantum computation, quantum network infrastructure, quantum sensor applications, and space-based communication systems during initial market introduction. Distributed architectures enable linking multiple smaller processing units into unified large-scale computational platforms, expanding total capability without centralized quantum hardware dependencies. Quantum networking enables protected optical connections, encryption key distribution, safeguarded data transmission, and next-generation internet backbone development.

Quantum sensor technology supports positioning systems, military applications, manufacturing oversight, and vital infrastructure operations independent of traditional GPS dependencies. Space applications focus on radiation-resistant photonic components for satellite platforms, encrypted communications, orbital infrastructure, and space-based quantum networking. SEALSQ anticipates establishing collaborations with governmental entities, telecommunications carriers, cloud infrastructure providers, research institutions, defense contractors, and industrial organizations requiring scalable quantum solutions.
