Evaluating the Accuracy of Quantum Computers through a Quantum Fourier Transform Algorithm

For my freshman lab class final project, Dorothy Gan, McKenna Leichty, and I I chose to work with quantum computers.


This paper presents a method of evaluating the accuracy of current superconducting quantum computers. A Quantum Fourier Transform algorithm was developed and run on multiple quantum computers as well as a simulation. The circuit was run on each machine 2048 times and the results were compared. The quantum computers resulted in an average of 75.20% measured in the |101⟩ state, indicating a 24.80% error when compared to the simulation which had measured 100% in the |101⟩ state as expected. Future experimentation could examine the accuracy on a wider array of quantum algorithms or compare different types of quantum computers such as trapped ions or quantum dots.
