Binary Subdivision for Quantum Search

arXiv:1101.4703

Abstract

We consider in this paper the possibility of embedding a quantum search algorithm within a classical binary search framework. The result appears promising: taking full advantage of quantum parallelism, we show that it may actually be possible to search an unstructured list in O(lg(N)), provided we are willing to restart the quantum search multiple times with a different sequence of qubits and perform a series of non-unitary measurements at the end of each.
