‘Father of quantum computing’ wins $3m physics prize

David Deutsch, who proposed an as yet unbuildable machine to test existence of parallel universes, shares prize with three others

A theoretical physicist who has never had a regular job has won the most lucrative prize in science for his pioneering contributions to the mind-bending field of quantum computing.

David Deutsch, who is affiliated with the University of Oxford, shares the $3m (about 2.65m) Breakthrough prize in fundamental physics with three other researchers who laid the foundations for the broader discipline of quantum information.
