The Prospect of Quantum Technologies in Space for Defence and Security
M. Krelina
Abstract
Quantum technologies will have enormous applications in space, especially in sensing and communication. Particularly, many current and future space assets are of dual-use character or specifically designed for military and intelligence purposes. This also applies to quantum technologies. In this contribution, we study possible space-born quantum technologies for defence and intelligence that have the greatest potential to exploit these technologies to the maximum and across the full spectrum of quantum technologies. Their utilisation will lead to joint networks of quantum sensing and quantum communications with other emerging technologies such as artificial intelligence and laser communication with deployment around the Earth. On the other side, space-based quantum technology design should reflect threats such as laser anti-satellite weapons in the case of larger conflicts.
