With the advent of quantum computers, traditional cryptographic methods face unprecedented threats.  In the latest episode of our podcast, we invited two guests from the Applied Security and Information Assurance (APSIA) Group at SnT (University of Luxembourg to discuss it: Prof. Peter Ryan and Dr. Peter Roenne.

Listeners will discover how quantum key distribution (QKD) works (or as Prof. Ryan calls it: quantum key establishment), leveraging the principles of quantum mechanics to create secure communication channels. The conversation also touches on the engineering challenges involved in implementing these technologies, particularly as we move toward a future where quantum computers may become a reality.
