qubithubquantum-fourier-transform

Quantum analog of the classical Discrete Fourier Transform. Transforms computational basis states into their frequency representation using O(n^2) gates — an exponential speedup over the classical FFT. The QFT is the core subroutine in Shor's factoring algorithm, quantum phase estimation, and many quantum simulation techniques.
