How does the QFT circuit relate to the classical fast Fourier transform (FFT) circuit?
Sunday, 06 August 2023 by EITCA Academy
The Quantum Fourier Transform (QFT) circuit is a fundamental component of Shor's quantum factoring algorithm, which is a quantum algorithm that can efficiently factor large integers. The QFT circuit is closely related to the classical Fast Fourier Transform (FFT) circuit, which is a widely used algorithm in classical signal processing and data analysis. In this
