SUMMARY

Shor's Algorithm utilizes the Quantum Fourier Transform (QFT) to efficiently factor large integers, a task that classical algorithms struggle with. The QFT transforms the input register into a superposition of states, allowing for the extraction of periodicity in the quantum state. This periodicity is crucial for determining the factors of the integer. Understanding the QFT is essential for grasping the full implications of Shor's Algorithm in quantum computing.

hey, from what I've read here: http://www.quantiki.org/wiki/index.php/Shor%27s_Algorithm , I understand most of the algorithm. The one thing that I don't get is what the quantum Fourier transform does to the input register. Can someone either explain how this works or what exactly it does?

thanks, that was pretty helpful. However there is almost no math or quantum mechanics in that article. All I understood was his metaphor for the QFT, not really the DFT.
