量子傅里叶变换和量子相位估计是许多量子算法的关键组成部分，如找阶、因式分解等。本文研究了高维情形下量子傅里叶变换和相位估计的一般过程。它们可以看作是量子计算机主程序的子程序，并给出了量子电路。
The quantum Fourier transform and quantum phase estimation are the key components for many quantum algorithms, such as order-finding, factoring, and etc. In this article, the general procedure of quantum Fourier transform and phase estimation are investigated for high dimensional case. They can be seen as subroutines in a main program run in a qudit quantum computer, and the quantum circuits are given.
