Google AI, Caltech, Purdue University advance quantum machine learning

When quantum computers start to learn, the rules of machine learning change. Machine learning has become deeply intertwined with human life, and any advances in the field are likely to yield broad socioeconomic benefits. In this work, Google AI’s team, in collaboration with Caltech and Purdue University, demonstrates groundbreaking advances in generative quantum machine learning. They succeed in striking a balance between algorithmic complexity (to go beyond easy classical simulability) and simplicity (to avoid trainability issues that often plague quantum machine learning methodologies), showcasing the capacity of quantum computers to learn beyond classical probability distributions. The methodology also enables the generation of efficient quantum circuits for improved simulation of physical problems. While questions remain about how sampling algorithms such as this will interplay with the overhead of error correction, this result represents a milestone in the promise of quantum machine learning and near-term quantum algorithms.
