Identifying nonclassicality from experimental data using artificial neural networks

Valentin Gebhart,
Martin Bohmann,
Karsten Weiher
et al.

Abstract: The fast and accessible verification of nonclassical resources is an indispensable step towards a broad utilization of continuous-variable quantum technologies. Here, we use machine learning methods for the identification of nonclassicality of quantum states of light by processing experimental data obtained via homodyne detection. For this purpose, we train an artificial neural network to classify classical and nonclassical states from their quadrature-measurement distributions. We demonstrate that the network… Show more

“…This comes in the framework of an exchange of concepts and methods between machine learning and quantum information. [11] Indeed, there have been demonstrations of the benefits of machine learning approaches to analyze data generated by quantum experiments, [12][13][14][15][16][17][18][19] to improve the performance of quantum sensors, [20,21] to Bayesian parameter estimations, [22] to the classification of non-Markovian noise, [23] and to the design of optical experiments. [24,25] Small gate-model devices and quantum annealers have been used to perform quantum heuristic optimization [26][27][28][29][30] and to solve classification problems.…”
