Researchers Explore How Quantum Computers—and Their Errors—May Enhance AI

Researchers at JQI and their collaborators explored how the probabilistic randomness of quantum computers, and their errors, may be beneficial to some AI models that are run on a quantum computer. By injecting various amounts of noise and quantum randomness during the operation of a basic AI model, the team determined that adding just the right amount improved its performance.

The central theme of my research is to apply tools from quantum science to the studies of molecular structures and chemical reactions. To this end, becoming a member of JQI, one of the world's leading quantum centers, is highly valuable for my research program. Conversely, I hope to leverage my interdisciplinary background in both AMO physics and physical chemistry to help foster synergy between quantum and chemical sciences at UMD.
