Insights
Strategic collaboration aligns post-quantum security tech with a CMOS-based scalable quantum platform, positioning both firms for secure quantum system design.
Combining SEALSQ post-quantum secure elements, TPMs, and Root-of-Trust frameworks with Quobly CMOS-compatible silicon spin qubit platform creates a direct mechanism to embed quantum-resistant security at the hardware design level. Embedding security early can reduce later integration friction and clarify technical requirements for secure control, cryogenic interfacing, and key-protection in large multi-qubit arrays.
Key dependencies and risks include the technical maturity of Quobly’s silicon spin qubits and the ability of SEALSQ’s algorithms and secure elements to operate in the target cryogenic and architectural constraints; both points must be validated through engineering milestones. The announcement does not disclose deliverables, timelines, or funded programs, so near-term commercial impact remains contingent on concrete integration outcomes.
Watch for demonstrable milestones such as joint technical prototypes, integration tests of Root-of-Trust elements with cryogenic control electronics, or publicized pilot programs in defense or critical-infrastructure environments within the next 12–36 months; the press date is
Geneva, Switzerland / Grenoble, France / Las Vegas, NV (USA), Nov. 21, 2025 (GLOBE NEWSWIRE) --
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.
