Abstract: We present several applications of quantum amplitude amplification to finding claws and collisions in ordered or unordered functions. Our algorithms generalize those of Brassard, Hyer, and Tapp, and imply an O(N^{3/4} log N) quantum upper bound for the element distinctness problem in the comparison complexity model. This contrasts with \Theta(N log N) classical complexity. We also prove a lower bound of \Omega(\sqrt N) comparisons for this problem and derive bounds for a number of related problems.
