PRESS RELEASE — SEALSQ Corp. (NASDAQ: LAES), (“SEALSQ” or “Company”), a global provider of post-quantum semiconductor technologies and hardware-anchored security solutions, and Quobly, a pioneer in silicon-based quantum microelectronics, today announced a collaboration to explore the convergence of secure semiconductor architectures and scalable quantum systems.
A collaboration at the intersection of large-scale quantum computing and secure hardware
This collaboration connects SEALSQ’s expertise in post-quantum security technologies with Quobly’s scalable silicon-based quantum computing platform. The companies will work together to assess how advanced security hardware and quantum processing architectures may co-evolve as quantum computing moves closer to industrial deployment, with the ambition to become the first players capable of exploring hardware Root-of-Trust and post-quantum cryptography natively integrated into large-scale, fault-tolerant quantum systems,
A partnership that aims to position QUOBLY and SEALSQ at the heart of the secure quantum future.

By combining SEALSQ’s field-proven post-quantum cryptography and Root-of-Trust technologies with Quobly’s unique CMOS-compatible silicon spin qubit platform, the two companies plan to define how quantum-resistant security can be natively embedded into tomorrow’s large-scale quantum systems from the earliest design stages.
This collaboration is set to deliver clear strategic benefits for both companies:
- Leadership in quantum-secure hardware: Early access to one of the world’s most advanced and scalable silicon qubit platforms enables SEALSQ to tailor its post-quantum secure elements, TPMs, and Root-of-Trust solutions to the exacting requirements of future fault-tolerant quantum computers.
- Accelerated relevance in high-stakes markets: Defense agencies, intelligence communities, financial institutions, and pharmaceutical leaders increasingly demand quantum systems that are both powerful and provably secure. This partnership positions SEALSQ as the go-to security layer for these mission-critical applications. Quobly will benefit from this collaboration to strengthen its development on security segment.
- Accelerated growth on U.S. Market: The alliance supports SEALSQ and Quobly’s expansion in the United States, where trusted hardware, post-quantum security and high-performance computing are increasingly strategic. It reinforces Quobly’s positioning in sectors such as defense, security, and critical infrastructure, where secure and scalable computing architectures are essential.
