@article{Harney2019EntanglementCV, title={Entanglement classification via neural network quantum states}, author={Cillian Harney and Stefano Pirandola and Alessandro Ferraro and Mauro Paternostro}, journal={New Journal of Physics}, year={2019}, volume={22} }
The task of classifying the entanglement properties of a multipartite quantum state poses a remarkable challenge due to the exponentially increasing number of ways in which quantum systems can share quantum correlations. Tackling such challenge requires a combination of sophisticated theoretical and computational techniques. In this paper we combine machine-learning tools and the theory of quantum entanglement to perform entanglement classification for multipartite qubit systems in pure states…
