Quantum communication, protocols & technology is a research area focused on exploiting quantum mechanical phenomena—such as superposition, entanglement, and no-cloning—for the transmission, processing, and security of information across quantum and hybrid quantum‑classical networks. It encompasses theoretical design and analysis of communication protocols (e.g., quantum key distribution, entanglement distribution, quantum teleportation, and quantum repeaters), physical implementations using diverse platforms (photonic, solid‑state, and atomic systems), and engineering of network architectures, error mitigation, and interface technologies. The field aims to realize scalable, high‑fidelity quantum networks and to integrate quantum communication primitives into broader quantum information processing and cryptographic infrastructures.
