SEALSQ Corp, a leader in post-quantum cybersecurity, has announced its intent to acquire Miraex SA, a specialist in quantum interconnect solutions. The companies signed a Letter of Intent, marking a significant step towards integrating Miraex's advanced photonics technology. This strategic acquisition, expected to finalize by the end of June 2026, aims to bolster SEALSQ's capabilities in the rapidly evolving quantum sector.
A Strategic Move in Quantum Technology
The proposed acquisition is a pivotal move for SEALSQ, leveraging its Quantum Fund to enhance its technological portfolio. Miraex, based at the EPFL Innovation Park, develops critical photonics-based solutions that connect quantum processors with quantum networks. This technology is essential for building scalable and interconnected quantum systems for future applications.
Miraex specializes in Photonic Integrated Circuits using advanced Thin Film Lithium Tantalate technology. This platform operates across key areas including distributed quantum computing, quantum sensing, and the development of a future quantum internet. The company's expertise provides a foundational component for next-generation quantum infrastructure and secure communications.
Completing the Quantum Vertical Stack
This acquisition is central to SEALSQ's vision of creating a fully integrated Quantum Vertical Stack. The strategy encompasses the entire spectrum of quantum technology, from secure semiconductors to quantum hardware. Miraex's platform addresses a crucial missing piece by providing the necessary interconnectivity between different quantum components.
Miraex’s technology masterfully bridges the gap between the microwave frequencies used by quantum processors and the optical frequencies needed for communication. This capability is fundamental for any distributed quantum architecture, enabling seamless information transfer. Furthermore, its compact chip designs can be integrated into SEALSQ’s existing semiconductor roadmap.
Bolstering Space-Based Quantum Initiatives
The integration of Miraex is expected to significantly accelerate SEALSQ’s Quantum Spatial Orbital Cloud (QSOC) initiative. This ambitious program aims to deploy quantum-secure capabilities in Low Earth Orbit and beyond. Miraex's technology is uniquely suited for the demanding requirements of space-based quantum infrastructure.
The company's photonic circuits are compact, power-efficient, and inherently radiation-tolerant, which are critical attributes for satellite payloads. Their small form factor allows for deployment on smaller satellites, such as nanosatellites within the QSOC constellation. This alignment supports the development of scalable quantum networks across both terrestrial and orbital environments.
Leadership Perspectives on the Acquisition
Carlos Moreira, CEO of SEALSQ, highlighted the strategic importance of the deal for completing the company's quantum stack. He stated that Miraex's solutions form a critical interconnect layer, creating a more coherent architecture for their quantum capabilities. Moreira also emphasized that the acquisition will accelerate the company's vision for a quantum-secure infrastructure spanning both earth and space.
Daniel Brau, CEO of Miraex, expressed excitement about the opportunity to join forces with SEALSQ. He noted that Miraex's platform was designed to be the connective tissue of the quantum ecosystem. Brau believes SEALSQ’s global reach and semiconductor expertise will significantly advance their shared mission to connect quantum resources on a planetary scale.
Ultimately, the planned acquisition of Miraex by SEALSQ represents a calculated and forward-thinking move to solidify a leading position in the quantum technology landscape. By integrating Miraex's unique interconnect solutions, SEALSQ not only completes its vertical stack but also enhances its ambitious space-based quantum projects. This strategic union is poised to drive innovation and strengthen the development of next-generation secure communication and computing platforms.
