The Association for Computing Machinery has awarded the 2025 Turing Award to Charles Bennett and Gilles Brassard for their foundational work in quantum cryptography. Their invention of the BB84 protocol established a new paradigm of security based on the laws of physics rather than mathematical complexity.
Charles Bennett and Gilles Brassard have been awarded the 2026 Turing Award for their foundational work in quantum cryptography, specifically the BB84 protocol. Their research, which dates back to the 1980s, provides the theoretical framework for communication systems that are physically impossible to intercept without detection.
Charles Bennett and Gilles Brassard have been awarded the Turing Award for their foundational work in quantum cryptography, specifically the 1984 BB84 protocol. Their research established the first encryption method secured by the laws of physics rather than mathematical complexity, a breakthrough now central to global cybersecurity strategy.
