Minimizing the Reality Gap in Quantum Devices with Machine Learning

A major obstacle facing quantum devices has been solved by a University of Oxford study that leveraged machine learning capabilities. The results show how to bridge the “reality gap,” or the discrepancy between expected and observed behavior from quantum devices, for the first time. Physical Review X has published the findings.
