SEALSQ and Quobly Forge Alliance to Secure Quantum Computing’s Next Leap

SEALSQ and Quobly have announced a landmark partnership aimed at advancing secure quantum computing by integrating post-quantum cryptography directly into scalable, silicon-based quantum processors. The collaboration, revealed on November 21, 2025, brings together Switzerland-based SEALSQ—a leader in post-quantum security and secure semiconductors—and French quantum processor innovator Quobly. Their joint ambition is to embed quantum-resistant security mechanisms natively inside the next generation of quantum computing platforms, paving the way for large-scale, fault-tolerant systems that can be trusted for critical applications.

Quobly’s technology stands out for its fully silicon-based quantum processors that are compatible with standard industrial CMOS manufacturing. This approach allows Quobly to scale up to millions of high-fidelity silicon spin qubits—tiny quantum information units—on conventional wafers. Such scalability is crucial for transitioning quantum computing from experimental labs to robust, industrial deployment. By partnering with SEALSQ, whose Root-of-Trust hardware and post-quantum cryptographic solutions are already field-proven, the companies aim to define how security can be built into quantum systems from the earliest design stages, rather than as an afterthought.

According to The Quantum Insider, both companies see this integration as essential for the future of digital infrastructure. Maud Vinet, Co-Founder and CEO of Quobly, emphasized the importance of combining secure semiconductor technologies with advanced quantum computing:

“The convergence of secure semiconductor technologies and quantum computing is essential to protect the digital infrastructures of the future. By bringing together SEALSQ’s post-quantum Root-of-Trust technologies and Quobly’s scalable quantum platform, we are laying the foundations for sovereign quantum systems that Europe can fully control, trust, and industrialize.”

SEALSQ’s founder and CEO, Carlos Moreira, echoed this sentiment, highlighting the partnership’s role in accelerating “Europe’s path toward quantum independence.” The collaboration is positioned not just as a technological milestone, but as a strategic move to ensure Europe’s sovereignty over its quantum infrastructure—an increasingly urgent concern as quantum computing becomes central to national security, finance, and communications.

What Sets This SEALSQ-Secure and Quobly Collaboration Apart?

• Native Security Integration: Unlike typical approaches where security is layered on top of quantum systems, SEALSQ and Quobly are working to integrate quantum-resistant cryptography at the hardware level from the outset.
• CMOS Compatibility: Quobly’s processors leverage existing semiconductor manufacturing, enabling cost-effective scaling and easier adoption by industry.
• European Sovereignty: The collaboration aims to ensure that Europe can develop, control, and trust its own quantum infrastructure without relying on external technologies.

Industry Impact and Early Reactions

Initial coverage of the SEALSQ and Quobly collaboration has so far been limited to specialized quantum technology outlets, but the news is already attracting attention from industry experts. Analysts note the strategic significance for sectors where secure and scalable quantum computing is critical, including the Internet of Things (IoT), automotive systems, and satellite communications. The ability to embed post-quantum cryptography—designed to withstand future quantum attacks—directly into quantum hardware is seen as a game-changer for safeguarding sensitive data and infrastructure as quantum technologies move closer to real-world deployment

Looking Ahead
As quantum computing matures, the risks of quantum-enabled cyber threats increase. This partnership positions SEALSQ and Quobly at the forefront of developing quantum systems that are not only powerful but also inherently secure. By embedding post-quantum security into the fabric of quantum computing platforms, they are laying the groundwork for a new era of trusted digital infrastructure.
