SEALSQ Corp (NASDAQ: LAES) has entered into a non-binding Memorandum of Understanding (MOU) for the strategic investment and potential majority acquisition of Quobly SAS, a French pioneer in silicon-based quantum computing. The multi-stage transaction, anchored by SEALSQ’s recently expanded $100 million Quantum Fund, could result in a total investment of approximately $200 million. This move follows a strategic collaboration established in November 2025 and aims to create a vertically integrated platform that combines Quobly’s CMOS-compatible hardware with SEALSQ’s post-quantum “Root-of-Trust” security capabilities.
Quobly, a 2022 spin-off from CEA-Leti and CNRS based in Grenoble, specializes in developing quantum processors using standard 300 mm FD-SOI semiconductor manufacturing processes. This industrial approach allows Quobly to leverage the existing global microelectronics infrastructure to scale silicon spin qubits toward the millions required for fault-tolerant operation. The company is currently advancing its Q100T program, which targets the production of a 100-physical-qubit silicon chip by 2027. Quobly also maintains a strategic manufacturing partnership with STMicroelectronics, further reinforcing its “industrial-grade” roadmap.
Strategically, the acquisition is designed to establish a “secure-by-design” reference platform for quantum infrastructure. By embedding quantum-resistant security directly at the hardware level during the design phase, SEALSQ and Quobly intend to serve mission-critical sectors such as defense, intelligence, and financial services. According to SEALSQ CEO Carlos Moreira, the goal is to build sovereign, trusted quantum systems for Europe and its strategic partners, ensuring that future quantum infrastructures are resilient against the very threats that quantum computers themselves pose to traditional cryptography.
