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.
