A Novel Approach to Quantum Heuristics for Structured Database Search

Quantum Physics 2007-05-23 v1

Abstract

An algorithm for structured database searching is presented and used to solve the set partition problem. O(n) oracle calls are required in order to obtain a solution, but the probability that this solution is optimal decreases exponentially with problem size. Each oracle call is followed by a measurement, implying that it is necessary to maintain quantum coherence for only one oracle call at a time.
