QUANTUM FOURIER TRANSFORM
QWorld volunteer instructors
QWorld's free intermediate quantum programming workshop covering complex numbers, the quantum Fourier transform, and Shor's algorithm. The follow-on to QBronze, run as mentored online sessions through QWorld's global network.
A step-by-step explanation of the quantum Fourier transform: the circuit construction, why it is exponentially faster than the classical FFT, and its role in phase estimation and Shor's algorithm.
How Shor's algorithm breaks RSA encryption by factoring large numbers exponentially faster than any classical computer, and what this means for cybersecurity.
Build the Quantum Fourier Transform in Cirq one rotation at a time. Verifies against the classical DFT, explains the bit reversal, and shows where the speedup actually comes from.
Build the quantum Fourier transform circuit from scratch in Qiskit, understand why it works, and see how it underpins Shor's algorithm and quantum phase estimation.
