t 比特半经典量子Fourier 变换
量子Fourier 变换 Shor 量子算法 窗口法
2013/8/28
针对目前大维数量子寄存器生成的困难性, 研究了基于小维数量子寄存器实现大维数量子Fourier 变换的方法. 首先, 定义了t 比特半经典量子Fourier 变换, 从几率幅的角度证明该变换可以实现量子Fourier 变换, 且所需2 位量子门的规模显著降低, 并设计了该变换的量子实现线路. 然后基于t 比特半经典量子Fourier 变换, 将经典固定窗口法与Shor 算法实现方法相融合, 重新设...

In this paper we show how to use Grover's algorithm to amplify and enhance the period finding capability of the quantum Fourier Transform (QFT). In particular we create a quantum algorithm called the...

Using the finite Fourier transform, we introduce a generalization of Pauli-spin matrices for ddimensional spaces, and the resulting set of unitary matrices S (d) is a basis for d × d matrices. If N = ...
