Three-Qubit Implementation of Quantum Fourier Transform for Shor’s Algorithm

Quantum computers are capable of very fast computation as compared to the classical counterpart. Problems impossible for the classical computer are efficiently solved on a quantum computer. Shor's factoring algorithm (SFA) calculates the prime factors of a given number exponentially quicker than the available classical algorithm. The paper deals with a vivid explanation of the methodology and various other future possibilities related to the development of the SFA. The paper also emphasizes the three-qubit realization of the quantum Fourier transform on the IBM Q experience.
