This talk describes an efficient quantum algorithm for the Moebius function from the natural numbers to {-1,0,1} and discusses the algorithmic techniques used in this algorithm. While the Moebius function was previously known to be in BQP, here they present an algorithm that does not rely on factorization via Shor's algorithm as an intermediate step.
