en.Wedoany.com Reported - SEALSQ Corp has signed a $5 million commercial agreement with silicon-based quantum computing company Quobly, under which Quobly will integrate SEALSQ's post-quantum security technologies, secure semiconductor solutions, and related engineering and integration services.

This agreement represents a significant advancement in the strategic collaboration announced by the two companies in November 2025, following SEALSQ's strategic investment in Quobly. It marks the transition from strategic cooperation to commercial deployment, as Quobly accelerates the industrialization and commercialization of its silicon-based quantum computing platform after its recently completed €115 million Series A funding round.

Under the agreement, SEALSQ will provide Quobly with a range of post-quantum security technologies to protect the hardware, control systems, communication infrastructure, and trusted execution environments of next-generation quantum computing platforms.

The collaboration includes the integration and deployment of SEALSQ's quantum-resistant technologies, covering cryogenic CMOS ASICs, post-quantum secure semiconductor architectures and secure elements, hardware-based root-of-trust technologies, post-quantum cryptography based on standardized quantum-resistant algorithms, secure identity authentication technologies for quantum processors and control electronics, quantum-resistant PKI and trusted provisioning technologies, as well as engineering, integration, and security architecture services supporting the development of secure and scalable quantum computing platforms.

This commercial agreement combines Quobly's CMOS-compatible silicon spin qubit technology and scalable quantum processor architecture with SEALSQ's post-quantum semiconductor technologies and hardware-based root-of-trust infrastructure. The goal is to develop quantum computing systems that integrate cybersecurity directly into the hardware architecture from the earliest stages of system design. As quantum computers evolve from laboratory systems to industrial-scale infrastructure, securing quantum processors, cryogenic control electronics, classical computing systems, communication networks, and cloud interfaces becomes increasingly critical.

SEALSQ and Quobly aim to address this challenge by developing a security architecture in which quantum computing infrastructure can be authenticated, protected, and managed through hardware-based identity and post-quantum cryptography. Carlos Moreira, Founder and CEO of SEALSQ, stated that signing this $5 million commercial agreement is a significant milestone in executing SEALSQ's quantum strategy, demonstrating growing commercial demand for post-quantum semiconductor technologies. Carlos Moreira noted that the collaboration with Quobly is transitioning from strategic technology cooperation to commercial deployment. By integrating SEALSQ's post-quantum semiconductors, root-of-trust technologies, and security infrastructure into Quobly's scalable silicon quantum computing platform, both parties are building the security foundation required for next-generation quantum computers. Carlos Moreira believes that every quantum computer, every quantum data center, and every quantum communication infrastructure will ultimately require a trusted hardware security layer, and SEALSQ aims to become one of the world's leading suppliers of this quantum security infrastructure. Carlos Moreira also stated that the agreement validates the company's strategy of combining post-quantum semiconductors, secure hardware, and quantum computing technologies to create a vertically integrated and sovereign quantum technology ecosystem.

Maud Vinet, Co-founder and CEO of Quobly, stated that Quobly's mission is to develop scalable quantum processors using semiconductor technologies compatible with global CMOS manufacturing infrastructure. As quantum computing moves from research to industrial deployment and commercialization, security must be designed into the platform from the start, alongside scalability and manufacturability. Maud Vinet said that this agreement strengthens the technology roadmap by integrating advanced post-quantum security capabilities into silicon quantum computers, including the first-generation product Alloy Pioneer, which will be available via the cloud by the end of 2026. By combining Quobly's scalable silicon quantum computing platform with SEALSQ's expertise in post-quantum semiconductors and secure hardware, both parties are establishing a trusted and secure foundation for deploying next-generation quantum computing infrastructure.

Quantum computing infrastructure is expected to become increasingly interconnected, combining quantum processors, high-performance computing systems, artificial intelligence platforms, cloud infrastructure, and quantum communication networks. This emerging infrastructure will require new cybersecurity architectures capable of protecting systems from both traditional cyber threats and future quantum attacks. SEALSQ is developing a range of post-quantum semiconductor technologies designed to provide hardware-based identity, secure authentication, trusted execution environments, and quantum-resistant cryptography for interconnected devices and critical infrastructure. Through this commercial agreement with Quobly, these technologies are expected to be adapted and integrated into scalable quantum computing architectures.

Both companies believe that the combination of scalable silicon quantum computing and post-quantum hardware security technologies could create significant opportunities in strategic markets, including government and sovereign computing infrastructure, defense and national security, quantum data centers and high-performance computing, financial services, pharmaceutical and life sciences research, artificial intelligence infrastructure, critical infrastructure, and secure cloud computing. The agreement also supports broader goals of strengthening European technological sovereignty in quantum computing and post-quantum cybersecurity.

Quobly is developing quantum processors based on silicon spin qubits, manufactured using semiconductor technologies compatible with industrial CMOS processes. SEALSQ develops post-quantum secure semiconductors, secure microcontrollers, root-of-trust technologies, and trusted provisioning infrastructure, designed to protect interconnected systems and critical digital infrastructure. By combining these complementary technologies, both companies aim to contribute to developing a secure European quantum computing ecosystem capable of designing, manufacturing, protecting, and operating strategic quantum infrastructure.

In November 2025, SEALSQ and Quobly announced a strategic collaboration to explore the convergence of scalable quantum computing technologies and post-quantum hardware security. The newly signed $5 million commercial agreement represents the next phase of this relationship and establishes a framework for the commercial integration and deployment of SEALSQ technologies within Quobly's quantum computing development roadmap. The agreement demonstrates SEALSQ's strategy of converting its growing portfolio of quantum technology partnerships and investments into commercial opportunities for post-quantum semiconductors and root-of-trust technologies.
