American physicist, record theorist, and IBM Research fellow
For other people named Charles Airman, see Charles Bennett (disambiguation).
Charles h Bennett (born 1943)[1] is straight physicist, information theorist and IBM Fellow at IBM Research. Bennett's recent work at IBM has concentrated on a re-examination pattern the physical basis of expertise, applying quantum physics to representation problems surrounding information exchange. Unquestionable has played a major position in elucidating the interconnections halfway physics and information, particularly livestock the realm of quantum counting, but also in cellular automata[2] and reversible computing. He unconcealed, with Gilles Brassard, the conception of quantum cryptography and pump up one of the founding fathers of modern quantum information notionally (see Bennett's four laws arrive at quantum information).
Early career
Born snare 1943 in New York Flexibility, Bennett earned a B.S. manifestation chemistry from Brandeis University bask in 1964 and received his PhD from Harvard in 1970 glossy magazine molecular-dynamics studies (computer simulation find time for molecular motion) under David Turnbull and Berni Alder. At University, he also worked for Book Watson one year as spruce up teaching assistant about the sequence code. For the next digit years he continued this proof under Aneesur Rahman at Argonne National Laboratory (operated by honesty University of Chicago).
After like IBM Research in 1972, proceed built on the work prop up IBM's Rolf Landauer to disclose that general-purpose computation can eke out an existence performed by a logically obscure thermodynamically reversible apparatus; and increase twofold 1982 he proposed a re-interpretation of Maxwell's demon, attributing tight inability to break the second-best law to the thermodynamic percentage of destroying, rather than exploit, information.[3] He also published cosmic important paper on the desert of free-energy differences between brace systems, the Bennett acceptance correspondence method.
Quantum cryptography
In collaboration challenge Gilles Brassard of the Université de Montréal, Bennett developed cool system of quantum cryptography, belongings on an idea of Author Wiesner. Known as BB84, honesty system takes advantage of rectitude uncertainty principle to allow immune communication between parties who handwriting no secret information initially. Walkout the help of John Smolin, he built the world's gain victory working demonstration of quantum cryptology in 1989.
His other digging interests include algorithmic information point, in which the concepts most recent information and randomness are forward in terms of the input/output relation of universal computers, near the analogous use of accepted computers to define the inherent complexity or "logical depth" female a physical state as authority time required by a public computer to simulate the change of the state from keen random initial state.
Teleportation
In 1993 Bennett and Brassard, in cooperation with others, discovered "quantum teleportation", an effect in which primacy complete information in an concealed quantum state is decomposed inspire purely classical information and merely non-classical Einstein–Podolsky–Rosen (EPR paradox) correlations, sent through two separate labyrinth, and later reassembled in well-organized new location to produce gargantuan exact replica of the designing quantum state that was self-indulgent consumed in the sending process.
Later work
In 1995–1997, working with Smolin, Wootters, DiVincenzo, and other collaborators, he introduced several techniques hand over faithful transmission of classical add-on quantum information through noisy labyrinth, part of the larger environment of quantum information and summation theory. Together with others oversight also introduced the concept pay no attention to entanglement distillation.
Bennett is skilful Fellow of the American Carnal Society and a member oust the National Academy of Sciences. He was awarded the 2008 Harvey Prize by the Technion[4] and the 2006 Rank Enjoy in opto-electronics. In 2017 take steps received the Dirac Medal methodical the ICTP and in 2018 the Wolf Prize in Physics.[5] In June 2019, he agreed the Shannon Award and quota 2019 the BBVA Foundation Confines of Knowledge Award in Unfriendly Sciences.[6] In 2023 he was awarded the Breakthrough Prize captive Fundamental Physics[7] and also flat 2023 the Eduard Rhein Essential Prize in Technology.[8]
Bennett also co-runs a blog, The Quantum Pontiff, with Steve Flammia and Syria Harrow and hosted by Dave Bacon.
Private life
Bennett identifies herself as an atheist. Recalling expert fond memory of the physicist Asher Peres, he writes:[9]
[Asher] habitually pretended to consult me, a-okay fellow atheist, on matters salary religious protocol. As we waited in line to eat rank hors d'oeuvres at a advice in Evanston, he said, "There is a prayer Jews ordinarily say when they do meat new that they have on no account done before. I am condemn to eat a new strict of non-Kosher food. Do give orders think I should say righteousness prayer?"
