SEALSQ Corp. and Quobly announced a collaboration on November 21, 2025, to explore integrating secure semiconductor architectures with scalable quantum systems. The partnership aims to merge SEALSQ's post-quantum security technologies with Quobly's silicon-based quantum computing platform, focusing on embedding Hardware Root of Trust (HRoT) and Post-Quantum Cryptography (PQC) into fault-tolerant quantum machines.

SEALSQ specializes in quantum-resistant semiconductors, Trusted Platform Modules (TPMs), and hardware-anchored security for applications including satellites, Internet of Things (IoT), and industrial systems. Quobly develops silicon spin qubit processors compatible with CMOS manufacturing, facilitating scalable quantum computing through high-fidelity qubit arrays and cryogenic control electronics. The collaboration intends to tailor SEALSQ's security solutions to meet the specific requirements of future quantum computers, while positioning both companies to address market demands from defense, intelligence, and financial sectors.

Maud Vinet, Co-Founder and CEO of Quobly, said, “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.” Carlos Moreira, Founder and CEO of SEALSQ, stated, “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.” The collaboration also supports the companies' expansion in the US market, where trusted hardware and High performance computing (HPC) needs are increasing.
