Comparative Analysis of Quantum Adder Circuits in Computation Accuracy on Noisy Quantum Computers

초록

Since the advent of quantum computing, the accuracy performance of quantum adders in Noisy Intermediate-Scale Quantum (NISQ) computing has received significant attention. This paper analyzes the accuracy of exact quantum adders in the NISQ environment. Our results show the impacts of noise vary significantly on the quantum circuits, reaching up to 86%, 0.23, and 0.66 in error rate (ER), normalized mean error distance (NMED), and mean relative error distance (MRED), respectively. Furthermore, the bitflip noise model impacts the greatest on quantum adders, showing, on average, 12.20, 11.30, and 11.62 times higher values in ER, NMED, and MRED, respectively. These findings highlight that the accuracy of exact quantum adders is affected by NISQ computing.
