SEALSQ links nine quantum hubs from Spain to Switzerland and the US

Nine interconnected quantum hubs, spanning La Línea, Murcia, Toulouse, Meyreuil, Grenoble, Geneva, Lausanne, a future Swiss center, and Chicago, now form the backbone of SEALSQ Corp (NASDAQ: LAES) and its parent company WISeKey International Holding Ltd (SIX: WIHN; NASDAQ: WKEY). These companies are physically connecting layers of the SEALQUANTUM.com Sovereign Quantum Vertical Stack, from device manufacturing in Spain to infrastructure in Switzerland and a new transatlantic link to the United States. “The SEALSQ Quantum Highway is the map of our strategy,” said Carlos Moreira, Founder, Chairman and CEO of SEALSQ and WISeKey; the expansion implements a strategy focused on US-based quantum technology with EeroQ and extends operations beyond Europe. SEALSQ Quantum Highway: Nine Hubs Connecting Spain, Switzerland, and the US The physical infrastructure underpinning SEALSQ’s quantum ambitions now spans nine hubs, connecting locations in Spain, France, Switzerland, and the United States. This network, termed the SEALSQ Quantum Highway, is designed to integrate every stage of the SEALQUANTUM.com Sovereign Quantum Vertical Stack, from the initial fabrication of post-quantum devices to the operation of secure systems. Specifically, silicon designed in Grenoble and Provence undergoes manufacturing and personalization in Murcia, Spain, before potential integration into satellite devices assembled in La Línea, Spain. The expansion includes a transatlantic connection to Chicago, enacting a “Quantum Made in USA” strategy facilitated by a partnership with EeroQ. This move extends operations beyond European borders and reflects a deliberate focus on establishing domestic quantum capabilities within the US. More than $65 million of a planned $200 million investment in SEALQUANTUM.com has already been deployed, with an additional $100 million earmarked for deployment through the end of 2027. The company emphasizes that capital is strategically allocated to hubs that are both physically and contractually linked, ensuring a traceable chain of trust from design to operation. A recent $5 million agreement with Quobly, signed on July 10, 2026, exemplifies this approach, covering Cryo-CMOS ASICs and secure elements, and representing the first end-to-end contract executed along the Highway, originating in Grenoble and culminating in Geneva’s trust services. Each jurisdiction has either co-invested in a hub or formally validated its inclusion, demonstrating a commitment to sovereign quantum technology.

The Spanish Government supports Quantix in Murcia and the LLG4IR.com framework in La Línea, while the French Ministry of the Economy, Finance and Industrial and Digital Sovereignty approved the IC’ALPS acquisition and co-led Quobly’s Series A funding, EeroQ says. This support demonstrates a commitment to fostering quantum technology development within their respective nations. Switzerland’s Space Command completed a multi-year pilot program with WISeSat and SEALSQ in April 2026, and the US White House’s June 2026 Executive Order on quantum security underpins SEALSQ’s expansion, according to EeroQ. “When we launched the Quantum Corridor in La Línea in 2025, we said sovereign quantum technology would need physical infrastructure, not just intellectual property,” Moreira stated. “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.” The company plans to add a new center in Switzerland, further strengthening the Highway and its capabilities.

Tags: Ivy Delaney Ivy Delaney has been working with neural networks and machine learning since the mid-nineties, back when a couple of hidden layers and a long afternoon of training counted as ambitious. She has watched the field go from academic curiosity to the thing quietly running underneath everything, and she brings that long view to quantum computing.

For Quantum Zeitgeist she covers the ground where the two fields meet. That means quantum machine learning and the variational algorithms it leans on, and it also means the less glamorous but more interesting story of classical machine learning already doing real work inside quantum machines, decoding error-correcting codes, calibrating noisy hardware and learning the error models that simulators depend on. She writes about the hardware those algorithms have to run on too, and about the post-quantum cryptography scramble that the same hardware has set off. Her stories typically start with the paper, whether that is peer-reviewed work, conference proceedings or an arXiv preprint, with the source linked so you can hold a claim up against the research it came from. She is unimpressed by benchmarks that will not say what they beat, and by demonstrations that only work in the press release.
