Quantum Communications: How a Component of a Multi-Level Information Security Architecture Works

Quantum communications are now emerging as a promising direction for protecting information infrastructure, state information resources, corporate networks, and financial systems. They rely on the quantum states of physical information carriers to transmit data and distribute cryptographic keys. "The demand for developing quantum communications is driven by contemporary challenges: building quantum networks between production sites, protecting industrial IoT systems, securing automated production lines, and countering threats and potential…
