levelQuantum is a Milan-based deep-tech company providing unconditionally secure quantum key distribution (QKD) infrastructure for critical sectors including telecom, banking, defense, and government. Using a patented device-independent protocol (DI-QKD), levelQuantum generates encryption keys locally at each endpoint — meaning no key ever travels through the network — eliminating the root cause of cyberattacks: key compromise. The platform is infrastructure-agnostic, integrating directly with existing ICT systems across fiber, free-space, satellite, and drone channels. Backed by the European Commission (EIC), ESA, NATO DIANA, and with business partnerships, levelQuantum is transitioning from pilot deployments to commercial-scale operations.
