IBM Fellow and Quantum Pioneer Charles H. Bennett Receives A.M. Turing Award, Computing's Highest Honor

IBM Association for Computing Machinery New York

Charles H. Bennett helped pioneer the foundations of quantum information science alongside co-laureate Gilles Brassard of Université de Montréal.Bennett's more than five decades at IBM Research helped transform quantum theory into practical advances like quantum cryptography, teleportation, and entanglement-based protocols.He is the seventh IBM awardee recognized by ACM, the Association for Computing Machinery, with the A.M. Turing Award.The recognition joins IBM's long legacy of shaping quantum computing and the enduring impact of researchers who defined the field.designed to scale quantum systems alongside classical computing resources, helping solve problems that classical methods alone struggle to address. The company also debuted a credible path to build IBM Quantum Starling, which it expects to be the world's first large-scale, fault-tolerant quantum computer, and deliver it to customers in 2029.

ACM's award is named after Alan M. Turing, the British mathematician who articulated the mathematical foundations of computing. The 2025 award is the organization's first associated with quantum research and Bennett, who plans to donate part of his portion of a USD $1 million prize, is the seventh in a line of IBM researchers and scientists recognized for their work at the company.

Previous IBM-associated Turing Award recipients include John Backus (1977), honored for FORTRAN and the design of practical high-level programming systems; Kenneth E. Iverson (1979), recognized for APL and its influence on programming languages and notation; Edgar F. Codd (1981), for fundamental contributions to database management systems; John Cocke (1987), for advances in compiler theory, computer architecture, and RISC; Frederick P. Brooks (1999), for landmark contributions to computer architecture, operating systems, and software engineering; and Frances E. Allen (2006), the first woman to receive the award, for pioneering optimizing compiler techniques and automatic parallel execution.
