SEALSQ $5 Million Deal Integrates Post-Quantum Security into Silicon Qubits

A $5 million commercial agreement between SEALSQ (NASDAQ: LAES) and Quobly signals a shift toward deploying post-quantum security directly into silicon quantum computing platforms. The deal builds upon a strategic collaboration initiated in November 2025 and follows Quobly’s recent €115 million Series A financing, accelerating the industrialization of its silicon-based quantum technology. SEALSQ is not simply a software provider; the company is integrating post-quantum security hardware, including Cryo CMOS ASICs and secure semiconductor architectures, into Quobly’s systems. “The signing of this $5 million commercial agreement represents an important milestone in the execution of SEALSQ’s quantum strategy and demonstrates the growing commercial demand for post-quantum semiconductor technologies,” says Carlos Moreira, Founder and CEO of SEALSQ, as the two companies aim to build cybersecurity directly into the foundational hardware of future quantum computers.

SEALSQ and Quobly’s $5 Million Agreement for Post-Quantum Security Integration

This financial commitment focuses on more than software; SEALSQ is a semiconductor company actively integrating post-quantum security hardware directly into Quobly’s silicon quantum computing platforms. The agreement centers on Quobly integrating SEALSQ’s portfolio of quantum-security technologies, encompassing secure semiconductor solutions and associated engineering services. This includes Cryo CMOS ASICs for quantum computing architecture, post-quantum secure semiconductor architectures, and hardware-based Root-of-Trust technologies designed to authenticate quantum infrastructure. SEALSQ will also provide post-quantum cryptographic technologies based on standardized algorithms, secure identity solutions for quantum processors, and quantum-resistant PKI for trusted provisioning. This combined effort aims to build quantum computing systems with cybersecurity woven into the hardware from the design phase, addressing the growing need to protect processors, control electronics, and communication networks as quantum computers scale.

Moreira explained that the collaboration is transitioning from technology cooperation to commercial deployment, with SEALSQ’s semiconductors and Root-of-Trust technologies forming the security foundation for Quobly’s scalable platform. Maud Vinet, Co-Founder and CEO of Quobly, emphasized the importance of integrating security from the outset, stating, “As quantum computing moves from research to industrial deployment and commercialization, security must be designed into the platform alongside scalability and manufacturability.” This agreement will strengthen their technology roadmap by integrating advanced post-quantum security capabilities into Alloy Pioneer, Quobly’s first generation quantum computer available via the cloud by the end of 2026. The partnership also aims to bolster European quantum technology development by combining Quobly’s silicon spin qubit technology with SEALSQ’s secure hardware, creating a secure quantum technology ecosystem.
