SEALSQ Corp (NASDAQ: LAES) and its parent company WISeKey International Holding Ltd (NASDAQ: WKEY) announced the continued expansion of their Quantum Highway™, a sovereign technology infrastructure intended to link operations across Switzerland, Spain, France, the United States and India, with a planned extension into orbital infrastructure.

According to a press release, the network is designed to connect specialized centers covering semiconductor design, post-quantum security, photonics, quantum computing and satellite communications, rather than consolidating capabilities in a single location.

A planned Post-Quantum Semiconductor and Cybersecurity Center in the Canton of Jura, Switzerland, represents a major new component. The project contemplates an investment of CHF 40–60 million and has the potential to create approximately 150 jobs within five years and more than 250 over the longer term.

In Spain, Quantix Edge Security is developing semiconductor capabilities in Murcia, supported by a planned investment of approximately €40 million. In France, SEALSQ's subsidiary IC'ALPS provides ASIC and mixed-signal design capabilities alongside the Grenoble technology ecosystem. In the United States, SEALSQ's investment in EeroQ connects the infrastructure to quantum computing based on electrons on helium. In India, cooperation with Kaynes targets post-quantum semiconductor design, testing and secure personalization.

The space component, called the Quantum Spatial Orbital Cloud (QSOC), involves plans to combine post-quantum technologies with satellite connectivity through WISeSat, with a roadmap contemplating up to 100 satellites.

Carlos Moreira, Founder and CEO of WISeKey and SEALSQ, stated: "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."
