摘要
We compute lower bounds for the exact quantum query complexity of a ternary function f. The lower bound is of order O(log(3)(n)). In case f is symmetric on a sphere then the lower bound is of order O(root n). This work is a natural continuation of the work of Beals, Buhrman, Cleve, Mosca, and de Wolf on lower limits for binary functions.
