David Deutsch (physicist)
David Deutsch (born May 18, 1953 in Haifa ) is an Israeli-British physicist in the field of quantum information theory .
Life
German studied mathematics and physics in Cambridge , Oxford and Austin and has held a chair at Oxford University since 2009 . He received the Dirac Prize in 1998 for his work on quantum computers, including how these machines could be implemented using quantum gates . For 2017 he was awarded the Dirac Medal (ICTP) .
Deutsch is one of the best-known representatives of the so-called many worlds interpretation of quantum mechanics. From the double-slit experiment in quantum mechanics, in his book The Fabric of Reality, Deutsch draws the conclusion that parallel universes have a very concrete influence on the universe, e.g. B. the intensity distribution of the photons in the double slit experiment , where individual particles without visible interaction partners create an interference pattern. The invisible partners are particles of other universes, even if these parallel universes are otherwise extremely difficult to access.
His analysis of time travel and the logical problems connected with it comes to the suggestion that one would inevitably not only have to travel in time but also into a "parallel universe"; the time traveler who gets into the time machine and the one who gets out of it would not be identical. Furthermore, he also evaluates the ability, ascribed to quantum computers, to solve certain NP problems such as the factorization problem in polynomial time, as a strong indication of the existence of parallel universes, which provide the necessary computing power through interference with our universe.
In his book The Physics of World Knowledge , he hypothesizes a physical definition of life .
The Deutsch-Jozsa algorithm is named after him.
