SEALSQ Corp, which specializes in semiconductor security and Post-Quantum Cryptography (PQC) solutions, has entered into a non-binding Memorandum of Understanding (MOU) to potentially invest in Quobly, a French company developing silicon-based quantum computers.
This MOU gives SEALSQ exclusive negotiating rights for a multi-stage transaction: an initial minority investment in Quobly, followed by a potential majority stake. If completed, the transaction would result in a total investment of approximately $200m.
Since 2025, the two companies have had an ongoing strategic collaboration that aims at establishing a reference platform for secure-by-design quantum computing. This seeks to define how quantum-resistant security can be embedded directly into future quantum infrastructures serving defense, intelligence, financial services, pharmaceuticals, and other mission-critical sectors.
Maud Vinet, Co-Founder and Chief Executive Officer of Quobly, commented: “This proposed transaction by SEALSQ marks an important step in Quobly’s industrial journey. Joining forces with a global leader in post-quantum security and semiconductor expert accelerates our ability to bring secure, scalable silicon-based quantum processors to market, and to expand internationally while consolidating our technological roadmap.”
Carlos Moreira, Founder and Chief Executive Officer of SEALSQ, stated: “The proposed acquisition of Quobly is fully aligned with our Quantum roadmap. As quantum computing becomes a strategic infrastructure, security must be embedded at the hardware level from day one. Quobly’s CMOS-compatible quantum technology, combined with SEALSQ’s post-quantum Root-of-Trust capabilities, creates a unique platform to build sovereign, trusted, and industrialized quantum systems for Europe, and their strategic partners.”
