Title: Quantum Key Distribution, quantum internet and their applications. Use cases for the CESGA-VQCC link.

Organized by: CESGA Quantum Communications Group and Fsas Technologies.

This workshop is aimed at professionals and researchers interested in quantum communications, particularly quantum key distribution. We will examine the evolution of information security, analysing classic vulnerabilities in the face of emerging threats and advanced quantum cryptography protocols (QKD). The architecture of the quantum internet and its application in critical infrastructures will be addressed, concluding with a technical study of real implementations in 5G networks and key management in networks on the CESGA-VQCC link.

Date: December, 19
Schedule: 10 am to 1.30 pm
Language: This workshop will be held mainly in English
ONLINE FORMAT
