SEALSQ Corp, a global provider of post-quantum semiconductor technologies and hardware-anchored security solutions, and Quobly, a pioneer in silicon-based quantum microelectronics, 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.
