SEALSQ and WISeKey Expand Quantum Highway™, Connecting Sovereign Technology Centers from Silicon to Quantum and Space

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.
