Effects of noise on information corruption in the quantum teleportation algorithm

In the quickly growing field of quantum computing, interference called “noise” causes discrepancies within the results of a quantum experiment. We aimed to observe the effects of noise on the quantum teleportation algorithm, which is used to transport the quantum state of one qubit to another qubit over distances. When the information in the teleportation algorithm is passed through noisy channels, the data can easily become corrupted. We conducted this study in order to observe the effects of noise on the information that travels through these channels. We aimed to understand the nature of the data corruption to help create improved and more faithful methods of data communication. Prior to conducting this study, we expected that the noise would have the most effect on the real and simulated backends and the least effect on the perfect backend. Through this study, we ran teleportation circuits on three different backends (a perfect simulation, a noisy simulation, and the real hardware) and compared the final results with our expected states. We observed that the predicted effects of noise on the information is accurate in some respects but that noise has the potential to drastically alter and corrupt the data. Moreover, the real hardware we used was far more susceptible to noise interference than the simulations. Our findings indicate that, to prevent the information from being compromised, other methods of noise reduction must be employed in conjunction with the quantum teleportation algorithm.
