SEALSQ Initiates Early Commercialization of Miraex Quantum Photonics Platform Following Strategic Acquisition

Acquisition Status: SEALSQ states it completed the 100% acquisition of Miraex SA on June 2, 2026, financed through its reported $200 million Quantum Fund.Technology Focus: Miraex is developing a Thin Film Lithium Tantalate photonic integrated circuit platform designed to enable microwave-to-optical quantum transduction.Commercial Direction: Initial commercialization efforts are focused on potential applications in distributed quantum computing, quantum networking, quantum sensing, and what the company describes as a Quantum Orbital Space Cloud.SEALSQ Corp (NASDAQ: LAES) announced on July 31, 2026, it is initiating early commercialization of quantum photonics technology developed by Miraex SA. The company states it completed the 100% acquisition of the Swiss firm on June 2, 2026, as reported in a Form 6-K filing. SEALSQ reports its $200 million Quantum Fund has deployed more than $65 million into strategic quantum technology investments. Miraex, headquartered at the EPFL Innovation Park in Ecublens, Switzerland, is positioned as a key component of SEALSQ’s quantum photonics activities within its Quantum Sovereign Vertical Stack.Miraex is developing a proprietary Thin Film Lithium Tantalate Photonic Integrated Circuit (TFLT PIC) platform designed to enable microwave-to-optical quantum transduction. The platform aims to enable coherent conversion of quantum information between microwave frequencies used by superconducting quantum processors and optical frequencies employed for long-distance quantum communications, with the goal of preserving quantum state properties. Quantum transduction remains an active research challenge, with key metrics such as conversion efficiency, noise, and fidelity not disclosed.Lithium tantalate material platforms support low-loss photonic integrated circuits compatible with volume manufacturing processes and radiation-tolerant environments. The TFLT PIC approach targets a critical interconnect challenge in distributed quantum architectures by linking quantum processors operating in the microwave domain to optical channels. According to Carlos Moreira, Chairman and CEO of SEALSQ, ownership of this capability is intended to complement SEALSQ’s broader quantum and cybersecurity portfolio, which includes secure semiconductors, post-quantum cryptography, quantum networking, distributed quantum computing, and secure satellite communications. No performance benchmarks or deployment timelines were disclosed.Initial commercialization efforts are focused on potential applications in four areas:Integration of Miraex is intended to strengthen SEALSQ’s long-term roadmap for sovereign quantum infrastructure that combines secure semiconductors, post-quantum cybersecurity, photonic quantum interconnects, trusted cloud computing, and secure space communications. The company plans to engage governments, defense organizations, cloud providers, telecom operators, and critical infrastructure operators. Commercialization of the technology also supports Switzerland’s position as a quantum innovation hub through the EPFL Innovation Park location and advances SEALSQ’s Root-to-Qubit strategy. The broader industry has not yet demonstrated large-scale, low-noise quantum transduction suitable for commercial deployment.SEALSQ is advancing Miraex photonics toward early commercialization, though key technical performance metrics and deployment readiness remain undisclosed.Find out more here.—Further articles, reports, and the latest quantum computing news may be found at The Qubit Report.SoftBank Corp. and Quantinuum released Quantum Computing Frontiers in July 2026, mapping quantum chemistry and topological data analysis against Quantinuum’s hardware roadmap.
