WebDec 22, 2024 · The inverse quantum Fourier transform is a computationally very efficient implementation to the inverse discrete Fourier transform in the form of tracing back IQFT to its tensor product decomposition. In the following, we take n = 2 N, where N is the number of quantum bit in a quantum computer and the basis ... Weband a quantum part. The classical part involves modular exponentiation via repeated squaring, which can be performed quickly. The quantum part involves a “quantum Fourier transform”. We will prove that in certain cases, the quantum Fourier transform can be constructed in polynomial time, wherein lies the efficiency of the algorithm.
WebThe quantum Fourier transform is the quantum implementation of the discrete Fourier transform over the amplitudes of a wavefunction. Detailed explanations can be found in references [1] and [2]. The QFT forms the basis of many quantum algorithms such as Shor’s factoring algorithm, discrete logarithm, and others to be found in the quantum ... Webi, and that the Fourier transform is an involution (since H N is its own inverse). Representing a function with respect to this basis revealed patterns speci c to the Z n 2 group structure. The main advantage of quantum computing, though, is that the Fourier transform over Z n 2 is e ciently computable on a quantum computer. The matrix that im ...
