“Acceptance Speech” Frontiers of Knowledge Award 2020 in Basic Sciences
Gilles Brassard
Acceptance speech by Gilles Brassard, winner of the 2020 Frontiers of Knowledge Award in Basic Sciences, who was honored alongside Charles Bennett and Peter Shor for their fundamental contributions to quantum computation and communication. His research with Bennett led to the BB84 protocol, considered a foundational development in quantum cryptography, which uses the properties of quantum physics to detect interception attempts during cryptographic key exchange and develop secure communication systems.
Brassard highlights the importance of quantum theory as the foundation of numerous contemporary technologies and its ability to open up new possibilities for processing and transmitting information. His career illustrates how collaboration between physics and computer science led to cryptographic methods that initially seemed far removed from practical applications. He also emphasizes t
