AI Efficiently Fixes Mistakes in Error-Prone Quantum Computers

By New Scientist  February 11, 2022

Artificial intelligence (AI) can eliminate errors from a group of quantum bits, thanks to Lorenzo Cardarelli and colleagues at Germany's RWTH Aachen University.  The researchers used a small quantum computer model to generate a quantum version of a machine learning autoencoder algorithm.

They fed data into the system to see which errors it produced, creating pairs of correct and error-saturated data with which they trained the quantum autoencoder to detect and fix errors.Cardarelli said the AI could be trained on a specific quantum computer and learn to correct errors unique to that system.

"This is almost like custom designing an error-correction code according to the characteristics of the particular hardware," said Sonika Johri at U.S.-based quantum computing firm IonQ.
