A Polynomial-Time Quantum Algorithm for Collision Problem

Quantum Physics 2008-02-03 v3

Abstract

In this paper, we give a quantum algorithm which solves collision problem in an expected polynomial time. Especially, when the function is two-to-one, we present a quantum algorithm which can find a collision with certainty in a worst-case polynomial time. We also give a quantum algorithm which solves claw problem with certainty in a worst-case polynomial time.
