The Association for Computing Machinery (ACM) has announced that the 2025 ACM A.M. Turing Award will be presented to American physicist Charles H. Bennett and Canadian computer scientist Gilles Brassard, in recognition of their outstanding contributions to laying the foundation of quantum information science and transforming secure communication and computing. Known as the 'Nobel Prize of Computing,' the award comes with a $1 million prize funded by Google. In 1984, the duo jointly proposed the BB84 quantum cryptography protocol, which enables the establishment of encryption keys secured by the laws of physics without relying on computational assumptions and can withstand attacks from quantum computers. Variants of this protocol have been applied in global quantum communication networks. Additionally, they introduced quantum teleportation in 1993 and conducted entanglement distillation work in 1996, laying a solid foundation for the development of quantum networks and the quantum internet. Their research spans the fields of physics and computer science, leaving a profound impact on multiple disciplines. Both the ACM President and the Chief Scientist of Google DeepMind have highly praised their contributions. Meanwhile, the United Nations has declared 2025 as the International Year of Quantum Science and Technology, signaling that future explorations in quantum information science will unfold in areas such as fault-tolerant quantum computing. Both Bennett and Brassard have already received numerous prestigious awards.
