SEALSQ & Quobly Seal $5 Million Post-Quantum Security Deal

A $5 million commercial agreement between SEALSQ (NASDAQ: LAES) and Quobly signals a shift from collaboration to commercial deployment of post-quantum security solutions for quantum computing. The deal will see Quobly integrate technologies from SEALSQ, including secure semiconductors and hardware-based Root-of-Trust, into its silicon-based quantum computing platform, which recently received €115 million in Series A financing. This addresses the growing need to secure quantum processors, control electronics, and communications networks as the technology moves toward industrial scale. “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,” said Carlos Moreira, Founder and CEO of SEALSQ.

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

This deal marks a transition toward deploying post-quantum security solutions directly into Quobly’s silicon quantum computing platforms, building on previous research. The financial commitment follows Quobly’s recent €115 million Series A financing, which is now being used to accelerate the industrialization and commercialization of its quantum technology. SEALSQ will provide a comprehensive portfolio of post-quantum security technologies, extending beyond software to encompass the hardware underpinning Quobly’s quantum systems, including Cryo CMOS ASICs for quantum architectures, post-quantum secure semiconductor designs, and hardware-based Root-of-Trust technologies intended to authenticate quantum infrastructure and connected systems. The collaboration aims to integrate these security measures at the foundational level, protecting quantum processors, control systems, communications networks, and trusted execution environments. Quobly’s focus on silicon spin qubits, compatible with existing CMOS manufacturing, is central to this integration.

According to Maud Vinet, Co-Founder and CEO of Quobly, the objective is to build quantum computing systems where security is designed into the platform from the start, alongside scalability and manufacturability. Their Alloy Pioneer, slated for cloud deployment by the end of 2026, will be among the first to benefit from this enhanced security architecture. The companies envision applications spanning government, defense, finance, pharmaceuticals, and artificial intelligence, all requiring robust protection against conventional and future quantum-enabled cyberattacks. This agreement is about building a secure and sovereign European quantum computing ecosystem, leveraging complementary technologies to design, manufacture, and operate strategic quantum infrastructure. The partnership demonstrates SEALSQ’s strategy of converting its investments into commercial opportunities for its post-quantum technologies, and positions both companies to address the increasing need for hardware-level security in the evolving quantum landscape.
