Chinese researchers are developing an airborne quantum communications network with drones as nodes

Quantum drones under development in China could lead to nigh unhackable airborne quantum communication networks, a new study finds.

Quantum mechanics makes possible a strange phenomenon known as entanglement. Essentially, two or more particles such as photons that get linked or “entangled” can, in theory, influence each other no matter the distance between them. Entanglement is essential to the workings of quantum computers, the networks that would connect them, and the most sophisticated kinds of quantum cryptography—a  means of information exchange that is impervious to hacking.
