ACM Announces 2025 A.M. Turing Award Recipients
March 18, 2026
Charles H. Bennett and Gilles Brassard are the recipients of the 2025 ACM A.M. Turing Award for their essential role in establishing the foundations of quantum information science and transforming secure communication and computing. Bennett and Brassard are widely recognized as founders of quantum information science, a field at the intersection of physics and computer science that treats quantum mechanical phenomena not merely as properties of matter, but as resources for processing and transmitting information.
Bennett, an American physicist at IBM Research, and Brassard, a Canadian computer scientist at the Université de Montréal, have collaborated over four decades incorporating quantum principles into computational models. Their work has influenced cryptography, algorithm design, computational complexity, learning theory, interactive proofs, and mathematical physics, while their research helped catalyze a generation of physicists and computer scientists to work across disciplinary boundaries.
The ACM A.M. Turing Award, often referred to as the “Nobel Prize in Computing,” carries a $1 million prize with financial support provided by Google, Inc. The award is named for Alan M. Turing, the British mathematician who articulated the mathematical foundations of computing.
“Bennett and Brassard fundamentally changed our understanding of information itself,” said Yannis Ioannidis, President of ACM. “Their insights expanded the boundaries of computing and set in motion decades of discovery across disciplines. The global momentum behind quantum technologies today underscores the enduring importance of their contributions.”
