HL 47: Focus Session: Quantum Technologies in Deployed Systems II

Donnerstag, 20. März 2025, 09:30–12:30, H17

Recent advancements in quantum cryptography, quantum computing, and quantum sensing are driving researchers to develop a universal quantum network*known as the quantum internet, which will enable secure connections among quantum computers, as well as to networks of quantum sensors, through quantum cryptography. Building a functional quantum internet is one of the most ambitious goals in quantum technology for the coming decades.

The focus sessoin aims to provide a comprehensive overview of the corresponding platforms and advances in quantum technologies, and is organized by Simone L. Portalupi (U. Stuttgart), Michal Vyvlecka (U. Stuttgart) and Michael Zopf (U. Hannover).
