SEALSQ Corp. (NASDAQ: LAES), a provider of post-quantum semiconductor technologies, and Quobly, a pioneer in silicon-based quantum microelectronics, have announced a collaboration to explore the convergence of secure semiconductor architectures and scalable quantum systems.
The partnership aims to natively embed quantum-resistant security into future large-scale, fault-tolerant quantum systems from the earliest design stages. SEALSQ will tailor its Post-Quantum Cryptography (PQC) secure elements, TPMs, and Root-of-Trust solutions to the requirements of future fault-tolerant quantum computers. Quobly develops fully silicon-based quantum processors compatible with CMOS manufacturing, leveraging the maturity of the semiconductor ecosystem to fabricate millions of high-fidelity silicon spin qubits on standard wafers.
This collaboration is intended to accelerate the development of sovereign quantum systems that Europe can fully control and industrialize. Quobly will benefit from the partnership to strengthen its development on the security segment, while SEALSQ gains early access to one of the most advanced and scalable silicon qubit platforms.
The alliance also supports both companies’ expansion in the United States, reinforcing their positioning in sectors such as defense, security, and critical infrastructure, where secure and scalable computing architectures are essential.
