SEALSQ Corp, a developer of semiconductors, Public Key Infrastructure (PKI), and post-quantum technology, has officially initiated the commercial rollout of its newly acquired quantum photonics technology from Swiss-based Miraex SA. The move follows SEALSQ’s 100% acquisition of Miraex in June 2026.
The strategic buyout serves as a cornerstone in SEALSQ’s overarching vision to establish the industry’s first Quantum Sovereign Vertical Stack—a unified technology infrastructure spanning post-quantum cryptography, secure semiconductor hardware, quantum computing, quantum networking, and quantum communications.
Strategic Integration & Sovereign Stack Expansion
Finalized on June 2, 2026, the transaction was backed by SEALSQ’s $200 million Quantum Fund (SEALQUANTUM.com), which has directed over $65 million into high-impact quantum technologies to date. Located at the EPFL Innovation Park in Ecublens, Switzerland, Miraex now serves as the anchor for SEALSQ’s quantum photonics developments.
“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.”

Pioneering Quantum Interconnect Architecture
At the center of Miraex’s portfolio is its proprietary Thin Film Lithium Tantalate Photonic Integrated Circuit (TFLT PIC) architecture. The technology bridges a critical gap in scalable quantum infrastructure by converting quantum data between microwave frequencies (utilized by superconducting quantum processors) and optical frequencies (required for long-distance optical communications).
SEALSQ is focusing its commercial deployment across four major high-growth sectors:
- Distributed Quantum Computing (DQC): Integration of individual quantum computers to develop scalable quantum supercomputing systems.
- Quantum Networking: Provision of photonic infrastructure for wide-scale deployment of Quantum Key Distribution (QKD) and future quantum networks.
- Quantum Sensing: Development of highly sensitive photonic technologies for applications in GPS-denied navigation, defense systems, industrial sensing, and infrastructure monitoring.
- Quantum Orbital Space Cloud (QOSC): Utilization of radiation-hardened photonic systems to safeguard space-based quantum networks and satellite communication.
Accelerating Global Quantum Adoption
Integration of Miraex’s photonics portfolio helps in achieving the objective of SEALSQ’s long-term approach to providing sovereign quantum infrastructure. By bringing together secure hardware, post-quantum cryptography, photonics interconnects, trusted cloud infrastructure, and space communications networks, SEALSQ strives to make the adoption easier for enterprises and governments via global strategic partnerships.
