本文描述了目前求解对称群上量子傅里叶变换(QFT)的最快量子算法。我们提供了一个新的FFT(经典)算法在对称群,然后将其转换为一个量子算法。我们的QFT算法的复杂度为O(n3 log n),比现有的O(n4 log n)QFT算法快。此外,我们表明,该算法可以在O(n 3),如果使用阈值门是允许的。
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.
