Quantum cryptography systems are among the most secure in the world because encryption keys are generated randomly and do not rely on mathematical algorithms. The Association for Computing Machinery (ACM) today announced that the 2025 Turing Award has been won by Charles H. Bennett and Gilles Brassard.
Bennett and Brassard are considered the founders of the field of quantum information, which combines quantum physics and computer science. It began with the BB84 Protocol they developed in 1984, which is the basis of quantum cryptography. It allows two parties to share a secret key with security guaranteed by the laws of physics. Any eavesdropping can be detected because quantum information cannot be copied without interference.
Charles H. Bennett is an American physicist who works at IBM. He is also a figure in the field of quantum teleportation and information theory. Before receiving the Turing Award, he won the Wolf Prize and the Breakthrough Prize.
Gilles Brassard is a Canadian computer scientist who is an early pioneer of quantum information. He is a Professor at the Université de Montréal. Like Bennett, he is also a recipient of the Wolf Prize and the Breakthrough Prize.
As winners of the ACM A.M. Turing Award, Bennett and Brassard received a $1 million prize from Google.
