Abstract
This article explains quantum computing and its potential for rendering current encrypted communication via public channels insecure. A review of quantum key distribution is given as a way to ensure secure public-channel communication regardless of the computational power of an adversary, that may possesses a quantum computer. Finally, state-of-the-art quantum key distribution is discussed with an insight into its future.
