This paper describes the fastest quantum algorithm at this moment for the quantum Fourier transform (QFT) over symmetric groups. We provide a new FFT (classical) algorithm over symmetric groups and then transform it to a quantum algorithm. The complexity of our QFT algorithm is O (n 3 log n), faster than the existing O (n 4 log n) QFT algorithm. In addition, we show that the algorithm can be performed in O (n 3) if the use of threshold gates is allowed.
