“David Deutsch and Quantum Constructor Theory.” Wikipedia says: “David Deutsch, born 1953 is an Israeli-born British physicist at the University of Oxford. He is a Visiting Professor in the Department of Atomic and Laser Physics at the Centre for Quantum Computation in the Clarendon Laboratory of the University of Oxford. He pioneered the field of quantum computation by formulating a description for a quantum Turing machine, as well as specifying an algorithm designed to run on a quantum computer. He is a proponent of the many-worlds interpretation of quantum mechanics.” On Edge.org, Deutsch describes his quantum constructor theory: “Some considerable time ago we were discussing my idea, new at the time, for constructor theory, which was and is an idea I had for generalizing the quantum theory of computation to cover not just computation but all physical processes. I guessed and still guess that this is going to provide a new mode of description of physical systems and laws of physics.” His latest book, “The Beginning of Infinity: Explanations That Transform the World” is on unlimited human possibilities.
