Ephos: Strategic Analysis of Italy’s Quantum Photonics Startup Strengthening European Technological Sovereignty
Ephos is a Milan-based deep-tech startup engineering a new breed of photonic chips on glass—a technological breakthrough poised to reshape Europe’s quantum and classical computing landscape. In an unassuming facility near Milan, this young company is quietly building what it calls the world’s first dedicated manufacturing line for glass-based photonic circuits. Such circuits leverage light instead of electricity to process information, and by using glass (the same medium as optical fibers) Ephos drastically reduces signal losses that plague traditional silicon photonics. The result is a platform of ultralow-loss, high-speed photonic chips that can power everything from quantum computers to next-generation data centers and secure communication networks. Backed by prominent venture investors and benefitting from European and NATO innovation programs, Ephos exemplifies the kind of strategic, home-grown technology venture that Europe increasingly views as critical to its technological sovereignty. The company’s vision aligns with broader EU and NATO efforts to secure supply chains and achieve independence in emerging technologies. Ephos stands at the nexus of Europe’s quantum ambitions and defense modernization, making it a compelling case study in strategic autonomy-in-action.
