Deep-learned classification of quantum correlations from collective measurements

Original language description

The paper suggests employing deep artificial neural networks (ANNs) for resource-efficient classification of quantum correlations based on collective measurements conducted in the geometry of entanglement swapping. ANNs are trained to categorize two-qubit quantum states into five mutually exclusive classes depending on the strength of quantum correlations exhibited by these states. The precision and recall of the ANN models are analyzed as functions of the quantum resources consumed, i.e. the number of collective measurements or shots performed. The results indicate that the ANN models outperform analytical solutions, as they are capable of distinguishing between classes intractable by analytical witnesses, can operate under a reduced number of measurement configurations, and significantly better cope with detection noise and imperfect quantum channels.
