We show that the quantum Fourier transform on finite fields used to solve query problems is a special case of the usual quantum Fourier transform on finite abelian groups. We show that the control/target inversion property holds in general. We apply this to get a sharp query complexity separation between classical and quantum algorithms for a hidden homomorphism problem on finite abelian groups.

BACKGROUND Reductions in underage drinking will only come about from changes in the social and cultural environment. Despite decades of messages discouraging parental supply, parents perceive social norms supportive of allowing children to consume alcohol in 'safe' environments. METHODS Twelve focus groups conducted in a regional community in NSW, Australia; four with parents of teenagers (n ...
