Sum over paths
WebThe probability of each final state is then obtained by summing over all such possibilities. This is closely tied to the functional integral formulation of quantum mechanics, also invented by Feynman—see path integral formulation . Webchosen to make the sum-over-paths take a simple form. This reformulation of quantum computation is interesting for several reasons. First, it reveals a connection between quantum computation and one of the central problems in algebraic geometry. Indeed, much of the development of modern algebraic
