ABSTRACT: The
present paper is focused on non-uniform quantum coins for the quantum random
walk search algorithm. This is an alternative to the modification of the shift
operator, which divides the search space into two parts. This method changes
the quantum coins, while the shift operator remains unchanged and sustains the
hypercube topology. The results discussed in this paper are obtained by both
theoretical calculations and numerical simulations.
