SEALSQ’s Quantum Highway: Building Trust in Silicon for Global Connectivity

SEALSQ Corp (NASDAQ: LAES) is forging a new path toward global connectivity by building what it calls a “Quantum Highway,” a fully integrated platform where “trust begins, in silicon.” Announced January 27, 2026, this initiative moves beyond isolated quantum development by embedding cryptographic identity and post-quantum security directly into hardware – ensuring inherent system trustworthiness. Beginning as a pilot project linking Spain, France, and Switzerland, the Quantum Highway now spans developments and partnerships across Europe, the US, Asia, and the UAE. This globally scalable architecture interconnects secure semiconductors, ASICs, and quantum computing systems, anchored by a physically secure hardware root key, promising “end-to-end trust continuity across classical, post-quantum, and quantum environments.” Quantum Highway Architecture Enables Global Sovereign Interconnection SEALSQ Corp is establishing a novel, vertically integrated approach to quantum security, moving beyond isolated hardware, software, and connectivity layers to embed trust directly within silicon—a platform where, as the company states, “trust begins, in silicon.” This isn’t simply about building quantum solutions; it’s about architecting a foundational layer of cryptographic identity and sovereignty for a post-quantum world. The initial groundwork was laid with a pilot “Quantum Corridor” connecting Spain, France, and Switzerland, demonstrating secure cross-border collaboration under a unified trust framework. This proof-of-concept has now blossomed into the “Quantum Highway,” a globally scalable architecture with active developments extending to India, the United States, South Korea, and the United Arab Emirates. The Highway isn’t merely a network; it’s an interconnection of secure semiconductors, ASICs, post-quantum cryptography, and quantum computing systems, all unified on a single platform. Central to this design is a “hardware root key,” physically secured within the silicon itself, establishing immutable device identity and governing the entire component lifecycle—from manufacturing through decommissioning. SEALSQ is actively solidifying this infrastructure through a strategic acquisition plan, including the 100% acquisition of IC’ALPS SAS (France) to bolster ASIC and custom chip design for critical applications. A €40M investment, alongside the Spanish government and WISeKey International Holding Ltd, fuels the Quantix EdgeS JV in Spain, focused on post-quantum RISC-V chip design. Further expansion includes a $10M investment in WISeSat.Space, developing a secure, post-quantum satellite-based IoT communications offering. These moves aren’t simply financial; they are designed to facilitate “deep technological integration, shared roadmaps, and coordinated R&D.” This ensures that quantum processors and hybrid systems are governed by the same security framework protecting SEALSQ’s existing chips, creating a “seamless, future-proof bridge” between current and future digital infrastructures.

As Carlos Moreira, Chairman & CEO, emphasizes, while quantum technologies will evolve, “trust, identity, and sovereignty remain stable across decades of innovation.” Strategic Acquisitions Expand Secure Semiconductor & Post-Quantum Capabilities SEALSQ Corp is aggressively reshaping the quantum landscape through a strategy of vertical integration, aiming to embed trust directly within silicon rather than layering security on as an afterthought. The company’s approach prioritizes a fully integrated architecture where cryptographic identity, post-quantum security, and sovereignty are foundational elements, beginning with a pilot project connecting Spain, France, and Switzerland. Strategic investments also include ColibriTD (France), focused on R&D collaborations to optimize semiconductor yields and mitigate side-channel attack risks, and a prospective investment in Quobly to integrate post-quantum security into quantum microelectronics. This long-term vision positions SEALSQ not simply as a quantum enabler, but as a builder of a durable trust infrastructure for critical sectors. By anchoring these principles in hardware, extending them through strategic acquisitions and investments, and scaling them globally via the Quantum Highway, SEALSQ is not only enabling quantum computing, it is also building a durable trust infrastructure for governments, critical infrastructure operators, and regulated industries seeking secure, sovereign, and resilient post-quantum and quantum solutions. Hardware-Rooted Trust Mitigates Quantum Computing Vulnerabilities This strategy addresses a critical vulnerability: the looming threat quantum computers pose to current encryption standards like RSA and Elliptic Curve Cryptography (ECC). SEALSQ recognizes that “as quantum computers advance, traditional cryptographic methods…are increasingly vulnerable,” necessitating a proactive, hardware-level solution. The company’s approach began with a pilot initiative linking Spain, France, and Switzerland, demonstrating the viability of secure cross-border collaboration leveraging this hardware-rooted trust. These include the full acquisition of IC’ALPS SAS (France) to strengthen ASIC design, and a $10M investment in WISeSat.Space to develop secure satellite-based IoT communications.
