We present a bounded-error quantum algorithm for evaluating Min -Max trees with $N^{\frac{1}{2}+o(1)}$ queries, where N is the size of the tree and where the allowable queries are comparisons of the form [x j x k ]. This is close to tight, since there is a known quantum lower bound of $\Omega(N^{\frac{1}{2}})$.
