SEALSQ Corp., a leader in post-quantum semiconductor security, has announced a strategic collaboration with Quobly, a trailblazer in silicon-based quantum microelectronics. The partnership aims to merge SEALSQ’s expertise in quantum-resistant Root-of-Trust technologies with Quobly’s CMOS-compatible silicon qubit platform to create quantum systems that are not only powerful but inherently secure.
Under this agreement, the two companies will explore how hardware-level security elements—like post-quantum cryptography and secure chips—can be integrated into large-scale, fault-tolerant quantum architectures from the ground up. The goal is to develop sovereign quantum systems that provide both compute power and built-in protection.
“At Quobly, our focus is on building scalable quantum processors using industrial-grade semiconductor technology. Exploring complementarities with post-quantum security is a natural step as quantum computing moves toward real-world applications. This collaboration with SEALSQ allows both teams to combine expertise to accelerate US market expansion and strengthen their positions in the defense and security sectors,” said Maud Vinet, CEO and Co-Founder of Quobly.

Carlos Moreira, CEO of SEALSQ, emphasized the strategic importance of the alliance: “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. This partnership strengthens the foundations for next-generation secure computing systems and accelerates Europe’s path toward quantum independence.”
Technologically, Quobly’s silicon spin qubit processors are built on established CMOS semiconductor processes, featuring cryogenic electronics and scalable architectures. On SEALSQ’s side, their offering includes quantum-resistant TPMs, secure elements, and Root-of-Trust designs optimized with post-quantum algorithms like CRYSTALS-Kyber and Dilithium.
The collaboration is expected to accelerate both firms’ presence in U.S. markets—especially in sectors like defense, financial services, and critical infrastructure where secure quantum systems could become essential.
