The quantum Fourier transform (QFT) is a fundamental operation in quantum computing that plays a important role in many quantum algorithms, including Shor's algorithm for factoring large numbers and quantum phase estimation. It is a quantum analogue of the classical discrete Fourier transform (DFT), with some important differences. In classical computing, the DFT is a
