Abstract: Shor’s quantum algorithm outperforms its classical counterpart in efficient prime factorizations. We explore the coherence and entanglement dynamics of the evolved states within Shor’s quantum algorithm. We show that the coherence relies on the dimension of register. We prove that the coherence of inverse Fourier transform relies on the order. We derive the complementarity relations between the coherence/entanglement and success probability, and show that the overall effect is that coherence is in depletion, while the variations of entanglement rely on the dimensions of each register, the order and the Hamming weights of the output states.
