Post-quantum semiconductor specialist SEALSQ Corp has finalized its acquisition of Swiss photonics developer Miraex SA, securing 100% of its shares1. This strategic integration was facilitated by SEALSQ’s SEALQUANTUM.com fund, which operates with a $200 million capital pool specifically allocated to establish a vertically integrated, sovereign quantum hardware value chain. The acquisition, the eighth by the fund, aims to complete SEALSQ's quantum sovereign vertical stack and advance its low-Earth orbit (LEO) satellite network initiatives. Miraex’s expertise in photonics is critical for developing the optical components essential for quantum communication and computing, enabling SEALSQ to consolidate key technological capabilities. This vertical integration strategy seeks to mitigate supply chain dependencies and bolster national security implications within the quantum domain. For cybersecurity professionals, this accelerating consolidation of quantum technology infrastructure by post-quantum specialists underscores the urgent need to prioritize cryptographic migration strategies and accelerate the implementation of post-quantum cryptography (PQC) solutions.
