In this note we study the number of quantum queries required to identify an unknown multilinear polynomial of degree d in n variables over a finite field F"q. Any bounded-error classical algorithm for this task requires @W(n^d) queries to the polynomial. We give an exact quantum algorithm that uses O(n^d^-^1) queries for constant d, which is optimal. In the case q=2, this gives a quantum algorithm that uses O(n^d^-^1) queries to identify a codeword picked from the binary Reed-Muller code of order d.
