Advanced Quantum Communication and Quantum Networks - From basic research to future applications — Björn Kubala, Alexander Sauer, •Alessandro Tarantola, and Matthias Zimmermann — German Aerospace Center (DLR), Institute of Quantum Techologies, Wilhelm-Runge-Straße 10, Ulm, 89081, Germany

The fast and reliable global classical communication enabled by the birth of the Internet brought about a cultural, economic and social revolution, and opened the door to previously unthinkable applications. Many observers believe a similar revolution is bound to take place, once the Quantum Internet, coherently connecting quantum devices (sensors, computers, memories,...), is established. In this talk, we provide an overview of concrete distributed quantum applications, mainly in the field of quantum security, that will be made feasible by the rise of the Quantum Internet. Moreover, we argue that the theoretical investigation of distributed quantum protocols is crucial in steering the next hardware- and infrastructure-development steps.
This talk is based on joint work within the “Physikalische Grundlagen der Quanteninformation, -kommunikation und -verarbeitung" project.
