Query: Fixed Phase Quantum Search Algorithm   Building quantum devices using fixed operators is a must to simplify the
hardware construction. Quantum search engine is not an exception. In this
paper, a fixed phase quantum search algorithm that searches for M matches in an
unstructured search space of size N will be presented. Selecting phase shifts
of 1.91684\pi in the standard amplitude amplification will make the technique
perform better so as to get probability of success at least 99.58% in
O(sqrt(N/M)) better than any know fixed operator quantum search algorithms. The
algorithm will be able to handle either a single match or multiple matches in
the search space. The algorithm will find a match in O(sqrt(N/M)) whether the
number of matches is known or not in advance.
