Geneva, Switzerland, Sept. 22, 2026 (GLOBE NEWSWIRE) --
SEALSQ Corp (NASDAQ: LAES) ("SEALSQ" or "Company"), a company that focuses on developing and selling Semiconductors, PKI, and Post-Quantum technology hardware and software products, and its parent company WISeKey International Holding Ltd (SIX: WIHN; NASDAQ: WKEY), today announced the continued expansion of the SEALSQ–WISeKey Quantum Highway™, an interconnected sovereign technology infrastructure designed to link strategic capabilities across Switzerland, Spain, France, the United States and India, and ultimately extending into space through WISeSat.
The SEALSQ–WISeKey Quantum Highway™ is designed to connect specialized centers of excellence rather than concentrate critical technologies in a single location. Together, these centers are intended to form an end-to-end chain of trust covering secure semiconductor and ASIC design, post-quantum security, semiconductor personalization, Root of Trust and PKI, photonics, quantum computing and quantum-secure satellite communications.
The Quantum Highway architecture spans: Silicon → Post-Quantum Security → Root of Trust → Photonics → Quantum → Space
A major new component is the planned Post-Quantum Semiconductor and Cybersecurity Center in the Canton of Jura, Switzerland. Previously announced by WISeKey, SEALSQ and the Republic and Canton of Jura, the project contemplates an investment of CHF 40–60 million and has the potential to create approximately 150 qualified jobs within five years and more than 250 over the longer term. The center would combine SEALSQ’s post-quantum semiconductor expertise with Jura’s internationally recognized capabilities in microtechnology, precision manufacturing and industrial engineering.
Jura could further strengthen a broader Swiss Quantum Technology Corridor connecting Geneva, Lausanne, Jura and space. Geneva provides WISeKey’s Root of Trust and PKI infrastructure; Lausanne contributes advanced photonics through Miraex; Jura would add semiconductor personalization, testing, certification and future ASIC capabilities; and WISeSat could extend this chain of trust into secure orbital infrastructure.
This Swiss corridor connects directly with the wider international Quantum Highway. In Spain, Quantix Edge Security is developing semiconductor capabilities in Murcia, supported by a planned investment of approximately €40 million, while La Línea de la Concepción provides an additional connection to post-quantum communications and WISeSat activities.
In France, SEALSQ’s operations provide secure-element and post-quantum semiconductor engineering, while its subsidiary IC’ALPS, provides ASIC and mixed-signal design capabilities. Together with the Grenoble technology ecosystem, these capabilities are positioned to support the development of emerging quantum-computing technologies. In the United States, SEALSQ’s investment in EeroQ connects the Quantum Highway with quantum computing based on electrons on helium. In India, cooperation with Kaynes is intended to develop local capabilities in post-quantum semiconductor design, testing and secure personalization while connecting these activities with the Group’s space ecosystem.
The final extension is space. Through the Quantum Spatial Orbital Cloud (QSOC), SEALSQ and WISeSat plan to combine post-quantum technologies, quantum-generated trust and satellite connectivity to create secure orbital infrastructure, with a roadmap that contemplates up to 100 satellites.
The result is an interconnected sovereign infrastructure spanning: Spain ↔ France ↔ Switzerland ↔ United States ↔ India ↔ Space
A secure semiconductor could therefore be designed in France, securely personalized in Spain, Switzerland or India, anchored to WISeKey’s Root of Trust in Geneva, interconnected through Swiss photonics, linked to quantum-computing environments in Europe or the United States, and ultimately extended into orbit through WISeSat.
As Carlos Moreira, Founder and CEO of WISeKey and SEALSQ, commented: “The Quantum Highway is becoming the physical map of our sovereign quantum strategy. We are connecting specialized centers rather than concentrating critical technologies in one location, creating an integrated chain of trust from semiconductor design and post-quantum security to quantum computing and space. We are building a chain of trust from silicon to quantum, and from quantum to space. Our objective is to build a trusted technology framework that extends from silicon to quantum and from quantum to space.”
