SEALSQ Begins Commercial Deployment of Miraex Quantum Photonics Technology

Insider BriefPress release – SEALSQ Corp (NASDAQ: LAES), (“SEALSQ” or “Company”), a company focused on semiconductors, PKI, and post-quantum technology solutions, today announced the start of the commercial phase of the groundbreaking quantum photonics technology developed by Miraex SA, following the 100% acquisition of the Swiss company in June 2026.The acquisition represented a major milestone in SEALSQ’s strategy to build the world’s first Quantum Sovereign Vertical Stack, integrating secure semiconductor hardware, post-quantum cryptography, quantum communications, quantum networking, and quantum computing into a single sovereign technology platform.Completed on June 2, 2026, the acquisition was financed through SEALSQ’s $200 million Quantum Fund (SEALQUANTUM.com), which has already deployed more than $65 million into strategic quantum technology investments. Miraex, headquartered at the EPFL Innovation Park in Ecublens, Switzerland, now becomes the cornerstone of SEALSQ’s quantum photonics activities.“This marks SEALSQ‘s transition from breakthrough research to commercial deployment,” said Carlos Moreira, Chairman and CEO of SEALSQ. “Miraex closes the quantum interconnect layer of our Quantum Sovereign Vertical Stack, the one piece the industry cannot scale without, and we now own it outright, acquired and funded through our $200 million Quantum Fund. That gives us an end-to-end offering no competitor can match today: secure semiconductors, post-quantum cryptography, quantum networking, distributed quantum computing, and secure satellite communications, delivered from a single sovereign platform. We are taking that stack to governments, defense organizations, cloud providers, telecom operators, and critical infrastructure operators worldwide. This is how a research pipeline becomes a revenue pipeline, and it is why we remain confident in our growth trajectory and our Root-to-Qubit strategy.”At the heart of Miraex’s technology is its proprietary Thin Film Lithium Tantalate Photonic Integrated Circuit (TFLT PIC) platform, capable of efficiently converting quantum information between microwave frequencies—used by superconducting quantum processors, and optical frequencies used for long-distance quantum communications. This technology solves one of the key challenges in scaling practical quantum computing and quantum networking.The commercial rollout initially targets four high-growth markets:The integration of Miraex significantly strengthens SEALSQ’s long-term roadmap to create sovereign quantum infrastructure combining secure semiconductors, post-quantum cybersecurity, photonic quantum interconnects, trusted cloud computing, and secure space communications into one unified ecosystem.The commercialization of Miraex’s technology also supports SEALSQ’s broader strategy of accelerating quantum adoption through strategic partnerships with hyperscalers, telecom operators, government agencies, defense organizations, research institutions, and industrial leaders seeking secure and scalable quantum infrastructure.With the launch of Miraex’s commercial activities, SEALSQ reinforces Switzerland’s position as a global hub for quantum innovation while advancing its vision of building sovereign quantum technologies designed to secure the digital economy for decades to come.TopicsShare Get the latest research, company news, and market intelligence every week.
