A Visiting Professor of physics at the Centre for Quantum Computation, the Clarendon Laboratory, Oxford University, and an Honorary Fellow of Wolfson College, Oxford, David Deutsch works on fundamental issues in physics, particularly the quantum theory of computation and information, and the new field of constructor theory.

In 1985, he wrote a pioneering paper that proposed the idea of a universal quantum computer, and then made some of the most important advances in the field, including his discovery of the first quantum algorithms. He is also a leading proponent of the multiverse (or “many worlds”) interpretation of quantum theory—the idea that our universe is constantly spawning countless numbers of parallel worlds.

Deutsch has been awarded with numerous prizes and honors, including the Micius Quantum Prize in 2018 and the International Centre for Theoretical Physics Dirac Prize in 2017. In 2008 he was elected a Fellow of the Royal Society. He has published numerous articles and research papers, presented three TED talks, and is the author of two popular science books on quantum theory, evolution, computation and knowledge creation: The Fabric of Reality and The Beginning of Infinity.

The rational attitude to the future is what I call the principle of optimism—all evils are caused by lack of knowledge.
