Towards the industrialisation of quantum key distribution in communication networks: A short survey Abstract Quantum information and communication technology will lead us to the new era of ultra‐fast and absolute‐secure networks. With the emergence of quantum supremacy on the horizon, the security of various classical encryption systems soon may be deemed obsolete. As a remedy, quantum key distribution (QKD) is proposed as a novel quantum‐based secret keys exchange, which is developed to solve ...
