SEALSQ Launches Commercial Phase of Miraex Quantum Photonics Technology Following Strategic Acquisition
Rhea-AI Summary
SEALSQ (NASDAQ: LAES) announced the start of the commercial phase of the quantum photonics technology developed by Miraex SA, following SEALSQ’s 100% acquisition of Miraex on June 2, 2026. The deal was financed via SEALSQ’s dedicated $200 million Quantum Fund, which has already deployed over $65 million into strategic quantum investments.
Miraex, based at the EPFL Innovation Park in Switzerland, becomes the cornerstone of SEALSQ’s quantum photonics activities and a key element of its planned Quantum Sovereign Vertical Stack, integrating secure semiconductors, post-quantum cryptography, quantum communications, networking, and computing. Central to Miraex’s offering is its proprietary Thin Film Lithium Tantalate Photonic Integrated Circuit platform, designed to convert quantum information between microwave and optical frequencies, addressing a core challenge in scalable quantum computing and networking.
The initial commercialization targets four segments: distributed quantum computing, quantum networking, quantum sensing, and a Quantum Orbital Space Cloud for secure satellite and space-based quantum networks. According to SEALSQ, integrating Miraex supports its long-term roadmap to create sovereign quantum infrastructure and advance secure, quantum-resistant technologies for governments, defense, cloud and telecom operators, and critical infrastructure worldwide.

Geneva, Switzerland , July 31, 2026 (GLOBE NEWSWIRE) --
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
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
“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
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:
- Distributed Quantum Computing (DQC): Interconnecting separate quantum processors to dramatically increase computing capacity and enable modular quantum supercomputers.
- Quantum Networking: Building the optical backbone required for large-scale Quantum Key Distribution (QKD) and the future quantum internet.
- Quantum Sensing: Delivering ultra-sensitive photonic technologies for navigation without GPS, defense systems, critical infrastructure monitoring, and industrial sensing.
- Quantum Orbital Space Cloud (QOSC): Providing radiation-tolerant photonic technologies for secure satellite communications and space-based quantum networks.
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.
