Abstract

Quantum technologies have the potential to improve communication security in network infrastructures in unprecedented ways. In this talk, after introducing the fundamental principles of quantum physics that enable the demonstration of such a quantum advantage, we discuss the current landscape of quantum communication and cryptography. In particular, we focus on experiments enabling the distribution of secret keys or the transaction of quantum money, with security guarantees impossible to achieve with classical resources alone. We also describe the current challenges in this field, such as the miniaturization of the systems developed, their integration into telecommunications network infrastructures, including satellite links, and their use with classical cryptography methods. These advances enrich the resources and applications of emerging quantum networks, which will play a central role in the context of future quantum-secure communications on a global scale.
