The age of computation is yet to come

Abstract

The theory of classical universal computation was laid down in 1936, was implemented within a decade, became commercial within another decade, and dominated the world's economy half a century later. This success story relied on the progress in technology. As computers become faster they must become smaller. The history of computer technology has involved a sequence of changes from one type of physical realisation to another, with smaller and smaller components. The unavoidable step to the quantum level will be one in this sequence; but it promises something more exciting as well. It can support entirely new modes of computation that do not have classical analogues. There is so much potential in this fundamentally new way of harnessing nature that it appears as though the age of computation has not yet even begun! © Selection and peer-review under responsibility of FET11 conference organizers and published by Elsevier B.V.
