Charles H. Bennett, IBM Fellow, receives A.M. Turing Award for quantum information work

Charles H. Bennett, an IBM research scientist and IBM Fellow, is co-recipient of the 2025 ACM A.M. Turing Award for foundational contributions to quantum information science, an honor he shares with Gilles Brassard.

Charles H. Bennett, an IBM research scientist and IBM Fellow, was named a co-recipient of the 2025 ACM A.M. Turing Award. The ACM credited his work with helping establish the field of quantum information science and with advancing how researchers think about computation and information. Over more than five decades at IBM Research, Bennett contributed to ideas and demonstrations such as quantum cryptography, quantum teleportation and entanglement distillation. He shares the award with longtime collaborator Gilles Brassard. What is known: - The 2025 A.M. Turing Award was announced by the Association for Computing Machinery and is shared by Charles H. Bennett and Gilles Brassard. - The ACM cited Bennett for contributions that helped spark a quantum revolution and for establishing quantum information science as a field. - Bennett helped develop the BB84 quantum cryptography protocol and was part of the first BB84 demonstration in 1989. - He co-authored a 1993 study introducing quantum teleportation and worked on entanglement distillation and related concepts that underpin much of modern quantum information science. - Bennett has worked at IBM Research for more than five decades and remains based at the IBM Thomas J. Watson Research Center in Yorktown Heights, New York. - The article reports Bennett plans to donate part of his share of the USD $1 million prize, and it notes IBM has described a path toward a large-scale, fault-tolerant system called IBM Quantum Starling with a target delivery year of 2029. Summary: The ACM award recognizes Bennett's foundational role in creating and advancing quantum information science and in moving theoretical ideas into experimental demonstrations. He shares the 2025 prize with Gilles Brassard, and Bennett has said he will donate part of his portion of the USD $1 million award. The reporting also notes IBM's ongoing work on scaling quantum systems and its stated plan toward a large-scale, fault-tolerant quantum computer with a 2029 target.
