Quantum communications for real-world use cases

Quantum key distribution (QKD) is a mature technology that establishes symmetric encryption keys between two remote parties in an unconditionally secure way. It has been successfully implemented in a variety of real-world scenarios, including cross-border networks, underwater links, and QMAN. In this paper, we present the latest results from our real-world implementations of QKD, demonstrating its adaptability and effectiveness in different environments.
