SEALSQ Expands Quantum Highway to Nine Hubs Across Four Countries

Insider Brief

• SEALSQ says its Quantum Highway now connects nine operational or planned hubs across Spain, France, Switzerland and the United States as part of its SEALQUANTUM.com strategy.
• The network links activities including semiconductor design, post-quantum personalization, secure-device manufacturing, quantum processor development, photonic integration, PKI and satellite operations across the nine hubs.
• SEALSQ says more than $65 million of its planned $200 million quantum initiative has been deployed, with another $100 million earmarked through the end of 2027 for additional assets and infrastructure.

PRESS RELEASE — SEALSQ Corp (NASDAQ: LAES) (“SEALSQ” or the “Company”), a global leader in secure semiconductors, PKI and post-quantum cybersecurity technologies, and its parent company WISeKey International Holding Ltd (SIX: WIHN; NASDAQ: WKEY) (“WISeKey”), today provided an update on the SEALSQ Quantum Highway, the physical and digital backbone of the Quantum Corridor first announced in July 2025. The Quantum Highway now interconnects nine operational or planned hubs across Spain, France, Switzerland and the United States, each hosting a distinct layer of the SEALQUANTUM.com Sovereign Quantum Vertical Stack.

The update follows the announcement that SEALQUANTUM.com, SEALSQ’s $200 million internal quantum initiative, enters its second phase of capital deployment this month, with more than $65 million already deployed and an additional $100 million earmarked for closing through the end of 2027. The SEALSQ Quantum Highway is the geographic expression of that strategy: capital is deployed into hubs that are physically and contractually connected, so that silicon designed in one location is manufactured, personalized, secured, launched and operated along a single auditable chain of trust.

The SEALSQ Quantum Highway: Nine Hubs, One Root-to-Qubit-to-Space Chain of Trust

Running from the Strait of Gibraltar to the Swiss mountains, and now across the Atlantic to Chicago, the SEALSQ Quantum Highway connects the following hubs:

How the Highway Works: Silicon Travels the Stack

The value of the SEALSQ Quantum Highway lies in the flows between its hubs rather than in any single site:

• A secure element or ASIC is designed in Meyreuil, Toulouse or Grenoble, on manufacturing platforms developed with GlobalFoundries under the SEALSQ–GF memorandum of understanding covering secure semiconductors, post-quantum cryptography and CryoCMOS.
• It is personalized in Murcia, where Quantix injects a unique, quantum-resistant identity anchored on the WISeKey Root of Trust operated from Geneva.
• It is integrated into post-quantum communication devices and WISeSat payloads manufactured in La Línea, or into Quobly quantum processors in Grenoble and, going forward, EeroQ systems in Chicago.
• It is interconnected through Miraex photonic chips from Lausanne, enabling quantum-secure links between processors, data centers and satellites.
• It is launched and operated through WISeSat and the QSOC program from Geneva, extending the same chain of trust into orbit, with a new center planned as the next integration and test facility on Swiss soil.

Each step generates commercial demand for the previous one. The $5 million SEALSQ–Quobly agreement signed on July 10, 2026, covering Cryo-CMOS ASICs, post-quantum secure elements, hardware Root-of-Trust, PKI and engineering services, is the first contract executed end-to-end along the Highway, from Grenoble design to Geneva trust services.

Sovereignty by Geography

The Highway deliberately spans four sovereign jurisdictions, each of which has co-invested in or validated a hub: the Spanish Government at Quantix in Murcia and the public-private LLG4IR.com framework in La Línea; the French Ministry of the Economy, Finance and Industrial and Digital Sovereignty, which approved the IC’ALPS acquisition, together with Bpifrance’s co-lead of Quobly’s Series A; the Space Command of the Swiss Armed Forces, whose multi-year pilot with WISeSat and SEALSQ completed in April 2026; and the United States, where the June 2026 White House Executive Order on quantum security frames SEALSQ’s Quantum Made in USA strategy with EeroQ.

Carlos Moreira, Founder, Chairman and CEO of SEALSQ and WISeKey, commented: “The SEALSQ Quantum Highway is the map of our strategy. When we launched the Quantum Corridor in La Línea in 2025, we said sovereign quantum technology would need physical infrastructure, not just intellectual property. Today a chip can be designed in Provence or Grenoble, personalized in Murcia, built into a satellite device in La Línea, interconnected with photonics from Lausanne, authenticated by our Root of Trust in Geneva and launched into orbit, and the same trusted foundation now reaches a quantum computer in Chicago. As SEALQUANTUM.com deploys its next $100 million, every new asset will be chosen for how it strengthens a hub on the SEALSQ Quantum Highway or adds a new one, starting with Switzerland to host the center.”

Next Milestones on the SEALSQ Quantum Highway

Through end-2027: deployment of the additional $100 million of SEALQUANTUM.com phase-two capital into assets accretive to the SEALSQ Quantum Highway, including the planned Quantum and Space Center which location is under discussion with several Cantons.

Q4 2026: first QSOC launch with SpaceX from the Geneva-operated WISeSat program; Quobly’s Alloy Pioneer first-generation quantum computer available via the cloud.

2026–2027: ramp-up of the Quantix personalization center in Murcia and of post-quantum device manufacturing in La Línea; completion of EeroQ’s financing round with SEALSQ as lead investor and start of PQC integration into EeroQ products.
